Mars or Bust is a roguelike deckbuilder where your hand is a stock chart, with a free demo released on itch.io on October 19, 2026. Each morning you bet on up to five company cards, watch prices move tick by tick, and sell before the closing bell; matching sectors and companies form hands that multiply your profit. Earn enough to fly to Mars or go bust.

Featured in roguelike browser games, games like Balatro

How a trading day works

1. Morning: draw company cards and bet on up to 5.
2. Market hours: the chart moves tick by tick. Hit Sell All when the time is right.
3. Closing bell: hands score as profit × multiplier.

You do not need to know anything about stocks: up is good, down is bad.
