Balatro
Balatro takes the humble poker hand and turns it into an addictive run-based card game, where jokers and modifiers stack into increasingly absurd score combos. It plays in short bursts, which makes it perfect for a commute, but the "one more run" pull is strong enough to eat an entire evening.
What earns it the top spot is restraint — no energy timers, no gacha pulls, just a tightly designed loop that respects your time and your wallet.
