About this game

No turns. No waiting. Just be faster.

BoltDuel is a real-time 1v1 Speed card duel. Both players slam cards onto the center piles at the same time, and the first to empty their hand and stock wins.

ALSO KNOWN AS
Speed goes by a lot of names. Spit, Slam, Nertz, Pounce. If you grew up playing any of them at a kitchen table, you already know this game.

HOW TO PLAY
A 52-card deck is split evenly between the two of you. Play any card one rank above or below the top of either centre pile. Aces wrap between King and 2. When neither of you can move, hit SPEED to flip a fresh card onto each pile. Empty your hand and your stock first and you win.

A BOT THAT DOES NOT ROLL OVER
Most Speed bots are either unbeatable or trivial once you spot the pattern. This one waits a different fraction of a second every time, the way a person does, across Easy, Normal and Hard. Beating Hard means you actually got faster.

WHAT ELSE IS IN THERE
• Challenge a friend by name and duel them as soon as they accept
• Ranked online duels, with an ELO rating that moves against your real opponent
• Global leaderboard, plus a profile keeping wins, losses, draws and win rate
• A lightning strike on every SPEED, over original synthesized music and effects
• Hint mode that highlights what you can legally play while you are learning
• Free to play, and the bot is one tap away when nobody is around

Matches take under three minutes. Play on the bus, or against the person sitting next to you.
Real-time 1v1 Speed card duel. No turns: both of you play at the same time.

What’s new

Buttons that are switched off are readable again instead of fading into their own background, and signing in on a second device now signs the first one out properly. Push notifications also register more reliably after the app has been left in the background for a while.
