Dopamine Swap

Dopamine Swap is a quick card-swapping score game built for short, tense runs. Each round shows one card and one opponent score. Swipe the card to reroll a random number from 1 to 100. When the timer reaches zero, the card on screen is locked in automatically. If your card is higher than the opponent score, you win the round and add that card to your score. If it is lower or tied, the run ends. Early rounds show the exact opponent score. Later rounds gradually hide the opponent behind a widening score range, making each final card feel riskier. Features: - Simple swipe-based card rerolls - Random card values from 1 to 100 - Timer-based automatic comparison - Fast rounds for quick retries - Opponent score hints that get harder over time - Local best score saved on your device - No account required
