House Rules 21
Gator
Blackjack, but every dealer plays by their own house rules. Work your way through nine dealers, each bending the rules of 21 in a different direction, build your bankroll, and unlock the modifiers, side bets, and card backs that turn a simple hand into a full run.
Overview
House Rules 21 takes the game you already know and hands it to nine dealers who don't play it straight.
Every dealer at the table has their own twist on blackjack — one pushes instead of busting on 22, another forces you to hit on a low total, another swaps a card on you mid-hand without asking. Beat a dealer's house rule and move on to the next, tougher table. Lose your last life and the run is over.
Read the table, not just your hand. Each dealer's rule changes what "correct" blackjack strategy even means — the same 16 that's an easy stand against one dealer can be a forced loss against another.
Build toward a run, not just a hand. Bankroll and lives carry across dealers. Bet carefully, know when a life is worth spending to survive, and unlock side bets and modifiers — Red/Black bonuses, Ace bonuses, Long Hand, Pure Stand, and more — that reward specific styles of play.
Make the table yours. Unlock new card backs as you climb, chase all the achievements, and carry your progress with you via Steam Cloud saves.
