Match, slap, win

Get matched

Tap play and quick matchmaking finds you a live opponent in seconds. Or pick a bot to warm up first.

Slap in order

Play any card one rank above or below the top of a centre pile. Aces wrap between King and 2. Both players go at once.

Empty your hand

Clear your hand and stock before your opponent to take the duel, bank the ELO, and queue the next one.

The classic, online

The Speed card game, reimagined

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 look inside
