Model note: Simplified $1-unit model using a favorable-rule, basic-strategy-style edge. Real rules can move this materially. This lab holds the unit size and session length constant so the comparison is readable. It does not recreate a casino, predict your result, or make a game “safe.”

Privacy note: the simulation runs in your browser and does not send or save inputs. It is educational probability content, not gambling advice, a strategy, a guarantee, or a recommendation to play.
What the challenge is testing
This is a controlled comparison, not a recommendation. Each run starts with $20 and uses twenty $1 units so the game models can be viewed on the same scale. The model deliberately leaves out bonuses, side bets, table minimums, comp systems, and personal strategy.
For the real configuration in front of you, check the game’s rules, paytable, RTP information, and the operator’s terms. Use the RTP, house edge, and volatility guide for the vocabulary, then compare the exact rules rather than a generic label.
Does the challenge tell me which game to play?
No. It shows why the same budget can behave differently across simplified game models. It does not account for your local rules, table minimums, strategy, or personal boundaries.
Why use $1 units?
A fixed unit makes the comparison readable. Real casino minimums can make a $20 budget behave very differently, which is one of the practical questions the lab cannot erase.
Why can a game with a small house edge still end at $0?
House edge is a long-run average, not a session floor. Short sessions can finish well above or below the average because individual outcomes vary.
