Royal Leak
Video Poker Strategy Trainer
Only for iPhone
Free
iPhone
Most video poker apps let you play. This one tells you exactly what each mistake cost — in expected value, hand by hand, against exact math rather than a lookup table.
Perfect play in 9/6 Jacks or Better returns 99.54%. This game cannot be beaten. The goal is to lose as slowly as the game allows — and Royal Leak exists to show you, hand by hand, exactly where you are losing faster than you have to.
A leak is a small, persistent, invisible loss. This app finds yours.
EVERY HAND, SCORED
Hold what you think is right and draw. Royal Leak evaluates all 32 possible holds against the full remaining deck and reports three numbers: the expected value of the hold you chose, the expected value of the best hold available, and the difference — the EV you gave up.
No lookup tables. No simplified strategy chart with exceptions the chart doesn't cover. The engine computes the real expectation for your exact five cards against your exact pay table, every hand, every time.
TWO GAMES
- 9/6 Jacks or Better — 99.54% at perfect play
- 9/6 Bonus Poker Deluxe — 99.64% at perfect play
Same evaluator, different pay schedule. Four of a kind pays 80 instead of 25; two pair pays 1 instead of 2. The correct strategy is not the same, and the app knows the difference.
THE SHORT-COIN TRAP
Below max bet, the royal flush pays 250 per coin instead of 800. That single change drops Jacks or Better from 99.54% to 98.37% and changes the correct hold on 3.4% of hands. Royal Leak tells you when you are betting short, what it costs, and when the right play actually changes.
Those figures are exact — enumerated over all 2,598,960 possible deals, not sampled.
TRACK WHAT MATTERS
- Bankroll in real money, across six denominations
- Play multiple lines per hand
- Running accuracy and cumulative EV given up
- Coin-in and estimated rewards at rates you set
- Full hand history, filterable to your mistakes only
That last one is the point. Turn on errors-only and you are looking at a list of every hand you got wrong, what you held, and what you should have held. That list is the leak.
FOR PLAYERS WHO WANT THE REAL NUMBER
This is a trainer, not a casino. There is no wagering, no real money, no purchases, no ads, no accounts, and no sign-up. Nothing you do leaves your phone.
If you play video poker and you have never seen what your actual return is versus the game's theoretical return, you are about to find out. It is usually worse than people expect, and it is almost always fixable.
