Speed, also known as Spit, is a classic two-player card game built on speed rather than turns. A 52-card deck is split evenly between both players, and both play at the same time onto shared centre piles. Any card one rank above or below the top card is a legal play, and Aces wrap between King and 2.
When neither player can move, a fresh card flips onto each pile to unblock the board. The first player to empty their entire hand and stock wins. BoltDuel keeps every one of those rules and adds live online matchmaking, an ELO leaderboard, three bot difficulties, and a lightning strike on every play.
A cosmic aether theme tuned for fast eyes. Clear cards, clear piles, and a lightning strike that lands with every move.

Both hands, shared piles, real time.

Climb the global ELO ranking.

Wins, losses, draws, win rate.
