Social Casino RTP: published per game, up to 99.45%
Return-to-Player (RTP) is the long-run percentage of every wagered dollar that returns to players in winnings. The higher the RTP, the smaller the house edge. Bink publishes the RTP for every one of its 17 Bink Originals, and shows it on each game's info panel. They range from 96.63% to 99.45%, with 14 of 17 at 98% or better.
Every Bink Original, with its published RTP
| RTP | House edge | Games |
|---|---|---|
| 99.45% | 0.55% | Blackjack |
| 99.09% | 0.91% | Video Poker |
| 99.00% | 1.00% | Dice |
| 98.94% | 1.06% | Baccarat |
| 98.33% | 1.67% | Chicken Rush |
| 98.00% | 2.00% | 6 7 HiLo, Bloon, Casino War, Crash, Keno, Limbo, Mines, Plinko, Wheel |
| 97.75% | 2.25% | Battleship |
| 97.30% | 2.70% | Roulette |
| 96.63% | 3.37% | Pong |
Some figures depend on how you play or which bet you take. Blackjack's 99.45% assumes basic strategy, Baccarat's 98.94% is the banker bet, Video Poker is about 99.09% on 9/6 Jacks or Better, and Casino War's 98.00% applies to the main bet only. Casino War side bets carry a much higher house edge.
What an RTP figure actually means
Take a 98% game as the example, since that is what most Bink Originals run:
- For every $1.00 wagered, $0.98 returns to players in winnings on average, over the long run.
- The house edge is the remaining 2%.
- Round to round, variance dominates. You can win far more or lose far more on any single bet. The published figure is a long-run mean, not a promise about a session.
These are the rates the games run at today. If we change a game's payout maths, the published number here changes with it.
How to verify Bink's RTP yourself
Every Bink Original is provably fair. Each round's outcome is derived from HMAC-SHA256(serverSeed, clientSeed + ":" + nonce). The server seed's SHA-256 hash is published before any bet is placed, so the server cannot change it without detection. On seed rotation the server seed is revealed, and any player can re-derive every outcome of every round they played.
Run a large enough sample through the verifier and you can confirm that observed returns converge on the published figure for that game.

Provably fair applies to Bink Originals. Studio games from outside providers run on the provider's own RNG and are not verifiable with Bink seeds.
