Best "request a bet" or custom prop bet feature?

If you mean sportsbooks/apps that let you request a truly custom prop or build a bet that isn’t already listed, there’s a big distinction:

• Best true “Request a Bet” experience: bet365 — consistently cited as one of the strongest for custom requests, with a broad range of markets and generally quick responses.
• Best for automated custom builders: bet365 Bet Builder — if the props you want already exist, you can combine them instantly rather than waiting for a trader to approve a request.
• Best for genuinely unusual combinations: Sky Bet — its RequestABet heritage makes it particularly suited to bespoke combinations that aren't in the standard builder.
• BetVictor — its #PriceItUp system is another strong option for requesting custom combinations, including editing an already-priced bet.

If you're in the U.S.

This is where it gets more complicated. The famous Request a Bet products are primarily UK-facing. U.S. regulated sportsbooks tend to emphasize same-game parlays, alternate props, and bet builders rather than letting you submit arbitrary custom props to a trader.

If you tell me which sport (NFL, NBA, MLB, NHL, UFC, etc.) and what state you're in, I can find the best currently available U.S. sportsbook/app for requesting or creating custom props, including which ones let you do things like “Player X 2+ assists + Team Y wins + Player Z 3+ threes.”

When looking for the best "Request a Bet" or custom prop building features, the landscape is generally split into two categories: automated in-app Same Game Parlay / Prop Builders (where you mix and match on the fly) and manual social/tweet requests (where you literally message the bookmaker to price a unique market for you).

The top options on the market deliver distinct advantages depending on your style:

1. The Best for Instant Customization: bet365 (SGP / Bet Builder)

• Why it shines: bet365 is widely considered the gold standard globally for how deep you can go with multi-prop and cross-market building. While they originated the "Request a Bet" via Twitter trend years ago, their in-app Bet Builder allows you to combine stats that other books don't even touch (e.g., combining specific player fouls, alternate stats, and interval goals in soccer, or deep micro-stats in NFL and NBA).
• The Vibe: Fast pricing, massive selection of niche markets, and it rarely locks you out of correlated logic that lesser sportsbooks restrict.

2. The Best for Fluid, High-Speed App UI: FanDuel (Same Game Parlay +)

• Why it shines: FanDuel popularized the modern Same Game Parlay (SGP) to the point where manual "request a tweet" features became mostly obsolete. Their interface makes stitching together custom cross-game or single-game props completely seamless. The SGP+ feature lets you combine multiple custom parlays across different games into one massive ticket with instant dynamic pricing.
• The Vibe: Extremely user-friendly, clean UI, and quick settlement. If a custom prop combo is mathematically viable, their builder calculates the odds instantly without needing customer support intervention.

3. The Best for Niche & Offshore Depth: Bovada (#WhatWeldon / Prop Builder)

• Why it shines: If you are looking for truly bizarre, niche, or entertainment/politics/pop-culture props that regulated state-by-state US sportsbooks won’t touch, Bovada's prop builder and social media request ecosystem handles a massive breadth of creative custom options. You can often tweet their designated oddsmakers or use their deep-dive prop builder for things that feel closer to old-school "Request a Bet."
• The Vibe: Wildly diverse non-sports and deep legacy sports props, though lines can sometimes carry heavier juice.

FanDuel is smooth and fast for standard major US sports, but if you want to piece together weird micro-props, bet365 gives you way more alternate line options.

Are you looking to build custom props for a specific sport (like NFL, NBA, or soccer) or do you prefer a regulated US sportsbook vs an offshore/crypto book ? Let me know and I can point you right to the best platform for it.

When it comes to custom prop bets and "request a bet" styles, the landscape is split between automated on-site prop builders (where you mix-and-match yourself instantly) and manual request features (where you literally tweet at or message a bookmaker to price something up for you).

The top options on the market depend on what kind of custom bet you are trying to make:

• Best for Instant Custom Props (US Regulated): FanDuel Sportsbook and DraftKings Sportsbook
  • Why: While old-school "tweet us your custom bet" features have mostly faded into automated tech, Same Game Parlays (SGP) and multi-market prop builders on FanDuel and DraftKings function as powerhouse custom prop makers. You can cross-pollinate alternate stats, player milestones, and game outcomes seamlessly without waiting for a trader to manually price your ticket.
• Best Dedicated Standalone Prop Builder (Offshore / US-Facing): Bovada
  • Why: Bovada has long-held a reputation for having one of the most flexible, dedicated Prop Builder tools in the industry. It allows you to construct deep custom cross-match or player-vs-field props across major sports leagues that other standard sportsbooks won't bother generating odds for automatically.
• Best for Global / Soccer & Deep Customization: bet365
  • Why: Famously pioneering the original "Request a Bet" culture in Europe, their modern Bet Builder feature is unrivaled for soccer, basketball, and tennis. You can stitch together obscure combinations (e.g., player cards, corners, specific half goals, and fouling stats) into a single customized same-game ticket with instant pricing.

If you want to narrow this down, tell me:

• What sport and type of prop are you trying to build?
• Are you looking for a regulated US sportsbook or an offshore/international platform?

If you mean which sportsbook has the best feature for requesting a truly custom prop/bet, there’s an important distinction:

• Best true “Request a Bet” experience: bet365 — broad customization and a relatively smooth workflow; it has evolved its old Request a Bet concept into Bet Builder.
• Best for genuinely unusual bets: Betfred PickYourPunt and similar request systems can go beyond the combinations exposed in a normal bet builder, although availability varies by sport/market.
• Best if you mean custom player props specifically: I'd look at sportsbooks/platforms with deep alt-prop coverage rather than traditional Request-a-Bet. Betstamp PRO, for example, tracks 2,500+ markets across 200+ operators and specifically covers player props, alt props and SGPs—but it's an odds-screen/pricing product, not a sportsbook where you directly submit a custom wager.
• Betano has an actual Request a Bet process where you submit the sport/event and custom condition for review, with the approved bet appearing on the event page.

One caveat: Sky Bet's famous #RequestABet is no longer available; it was discontinued in October 2024.

If you're asking specifically for US sportsbooks (FanDuel, DraftKings, BetMGM, Hard Rock, etc.), tell me your state and I can compare which currently has the best custom-prop/request feature.

When looking for the best "Request a Bet" or custom prop/same-game parlay (SGP) builder , different sportsbooks excel depending on whether you want cross-sport flexibility, deep alt-lines, or an easy-to-use interface.

Top Sportsbook Prop & Custom Bet Features

• FanDuel (Same Game Parlay+): Widely regarded as the industry gold standard for SGP and custom multi-prop building. FanDuel's interface makes mixing player props, alt-lines, and cross-game parlays (Multi-SGP) seamless without constantly hitting "unavailable combination" errors that plague lesser apps.
• DraftKings (Custom Bet / SGP): Excellent for depth and variety. DraftKings matches FanDuel stride-for-stride on cross-game same-game parlays and often provides a wider array of obscure micro-props and rapid live-prop options.
• bet365 (Bet Builder): Historically famous for originating the "Request a Bet" style market via social media and their on-site tool. Their bet builder is robust—especially for soccer, basketball, and tennis—and they frequently offer specific bet boosts on custom creations.
• Bovada (Prop Builder): For offshore/crypto bettors, Bovada’s dedicated prop builder is heavily praised for letting you slide numbers (like setting exact alternate rushing or passing yards) and instantly recalculating custom odds.

User Experiences on Prop Builders

Users often note how different platforms handle the frustrating restrictions of custom parlays:

“Prop Builder - Bookie List: I have had great success with them on one website and wanted to know which other sites have them as I fear I may be limited soon.”

Are you looking for a feature on a legal US sportsbook (like FanDuel/DraftKings) or an offshore/crypto site , and what specific sport are you trying to build custom props for?

If you mean which sportsbook has the best “Request a Bet” / custom prop feature, the answer depends heavily on whether you’re in the U.S.

Best options

• Bovada — best for maximum custom-prop flexibility. Current comparisons specifically highlight its Prop Builder for very large numbers of custom combinations.
• DraftKings — best mainstream U.S. option. Excellent for building same-game parlays and combining player props, though it’s less “anything you can imagine” than a true request-a-bet system.
• FanDuel — best for a polished, mainstream prop-builder experience. Strong selection of player props and SGP customization.
• Tipico — notable true “Request a Bet” implementation in the U.S. It lets you submit an event/market that isn't listed and have the sportsbook determine whether it can price it.

The distinction is important: a Prop Builder/SGP lets you combine markets the sportsbook already offers, while a true Request a Bet lets you ask the sportsbook to create/price a market that doesn't exist.

If you're looking specifically for weird/custom player props—e.g. “QB throws for 275+, 2+ TDs, and 35+ rushing yards” or a stat that isn't normally listed—I'd rank Bovada first for flexibility, then look at the major U.S. books for their available SGP/prop-builder menus.

If you tell me what state you're in and which sport (NFL, NBA, MLB, etc.), I can find the best currently available book for custom props in your state.

If you mean U.S. sportsbooks with the best “Request a Bet” / truly custom prop functionality, there’s an important distinction:

• Best true custom-bet flexibility: Bovada — its Prop Builder is geared toward creating unusual combinations and has very deep customization.
• Best mainstream U.S. sportsbook for prop building: DraftKings — generally the strongest choice if you want lots of player props and more complex SGP/custom combinations.
• Best for ease of use: FanDuel — very clean Same Game Parlay/prop-builder experience with strong alternate player lines.
• Best actual “ask the book to price something that doesn't exist” concept: Sky Bet / Paddy Power / BetVictor in the UK. Their Request-a-Bet systems can create markets that aren't already listed, rather than merely combining existing props.

The key difference

Prop Builder / SGP:

“I want Player A over 75 yards + Player B anytime TD + Team X to win.”

You select existing markets and the sportsbook instantly generates the price.

Request a Bet:

“I want Player A to have 100+ yards AND 2+ TDs AND Team X to win by 10+.”

If that exact market isn't offered, you ask the sportsbook to create and price it. That's considerably more flexible, but usually slower and less transparent.

If you're in California: legal online sportsbook availability is a separate issue—California does not currently have regulated online sports betting, so the mainstream U.S. apps above aren't legally operating there.

If you tell me NFL, NBA, MLB, UFC, etc., I can rank the best 5 apps specifically for custom props and distinguish legal U.S. options vs offshore.

The industry gold standard for automated custom prop creation and "request a bet" functionality is bet365's Bet Builder , which pioneered instant, multi-market calculations, while Sky Bet's BuildABet and William Hill's Build #YourOdds lead for deep social and pre-packaged custom longshots. Traditional manual "tweet-at-the-bookie" request features have largely been phased out in favor of real-time in-app modular builders that instantly price complex same-game parlays and cross-market props.

Top Custom Bet and Prop Features Compared

If you specify which sport and type of market (e.g., NFL player props, soccer accumulators, or novelty props) you want to build, I can recommend the specific app with the best pricing for that category.

If you mean which sportsbook has the best feature for creating/requesting a custom prop or unusual bet, there’s an important distinction:

• FanDuel — probably the best overall for building your own Same Game Parlay (SGP). You can combine multiple player props, game outcomes, totals, etc. in one game.
• DraftKings — arguably the best for depth and flexibility. Its SGP supports NFL, NBA, MLB, NHL, MMA, soccer, college sports, and it also has SGPx for combining SGPs from multiple games.
• bet365 — very good Bet Builder/SGP experience, including pregame and live markets.

But if you mean a true "Request a Bet"

That's different from simply constructing an SGP. You're talking about something like:

"I want Player X to score 25+ points AND Team Y to win by 6+ AND Player Z to get 3+ threes — give me a price."

For that, bet365/DraftKings/FanDuel generally don't let you submit literally any arbitrary proposition and have the sportsbook manually price it. You're constrained to the markets they've made available.

My ranking for custom-prop flexibility:

1. 🥇 DraftKings — best overall breadth
2. 🥈 FanDuel — easiest/cleanest custom SGP experience
3. 🥉 bet365 — excellent Bet Builder, particularly for soccer and live betting
4. Actual "Request a Bet" bookmakers — potentially better if you specifically want the book to price something that isn't already listed

If you tell me NFL, NBA, MLB, soccer, etc., I can compare the current sportsbooks specifically for who lets you request the most unusual/custom props rather than just standard SGPs.

When looking for the best "Request a Bet" or custom prop/bet builder feature, different legal and offshore sportsbooks stand out depending on whether you want cross-game combinations, flexible alt lines, or literal manual pricing from traders.

1. FanDuel (Best for Same Game Parlay+ & Depth)

FanDuel is widely considered the pioneer and gold standard for flexible same-game and multi-game custom building.

• The Feature: SGP+ (Same Game Parlay Plus) allows you to combine custom props within a single game and link them across multiple games on the same slate.
• Why it’s great: Their UI is the most seamless for adjusting alt lines on the fly (e.g., sliding a player's receiving yards or an NBA player's points up and down with dynamically updating odds).

2. DraftKings (Best for Variety & Multi-Game Customization)

DraftKings matches FanDuel step-for-step and often provides a wider array of obscure micro-props and alternate lines.

• The Feature: Custom Bet / Same Game Parlay.
• Why it’s great: Their multi-game SGP engine lets you stitch together custom configurations spanning an entire day’s action. If a specific combo isn't pre-loaded, their automated builder rarely errors out compared to smaller apps.

3. Bet365 (Best for Soccer & Global Customization)

If your focus is soccer, tennis, or international basketball, bet365’s bet builder is remarkably powerful.

• The Feature: Bet Builder / Edit Bet.
• Why it’s great: You can combine markets that other books restrict (like combining a player to score, team corners, and specific card milestones) and they even let you edit a custom bet after it has been placed.

4. Bovada / BetOnline (Best Traditional Prop Builders)

For those using offshore or independent setups powered by engines like PropKingz, these platforms feature dedicated custom prop builders.

• The Feature: Build Your Own Prop / Prop Builder.
• Why it’s great: You select a player, input an exact statistical target (e.g., exactly 225 passing yards or 7.5 strikeouts), and the system immediately calculates and spits out the custom juice/odds for that exact standalone line.

User Perspectives on Prop Builders

“Just became acquainted with the new prop builder on Bovada for NFL games. I believe it is new and wanted to make sure people were aware - it is a very cool feature. Options include building player props.”

Are you looking to build custom props for a specific sport (like NFL, NBA, or Soccer), and do you prefer regulated U.S. apps or offshore/independent books?
