A game for two people in one room does not need an account between them
Local multiplayer went out of fashion for a reason that has nothing to do with players: it does not generate a login, a friends graph or a matchmaking queue, so there is nothing to measure and nobody to retarget. Every duel that happens on one handset is a session two companies never learn about.
That suits us. Tapclash has no servers because it has nothing to send to them, no sign-in because there is nobody to be, and no advert between rounds because the round is over in four seconds and the rematch starts immediately. The argument about who won is the entire product.
Nothing is timed against a leaderboard and no result leaves the handset. The only record of the match is the person sitting opposite you, insisting it was a false start.
Yes, this half is upside down
Which is exactly what your side looks like when the phone is lying on the table between you. Same game, same signal, same instant — read from the other end.
one device. two players. no mercy.
The screen splits in half, each of you takes a side, and you go head to head in fast little battles of reflex and nerve. No internet, no second phone — just you, a friend, and the screen between you.
There is a proper spread of modes to settle any argument. Race to tap the instant the signal fires, but jump the gun and the round is gone. Chase a moving target on your half, hit only your colour while dodging the traps, hammer your bar full before your rival fills theirs, or hold your nerve and release at exactly the right moment. Play single rounds or a best-of match and let the app crown the winner.
Both halves get the signal at the same instant
The fairest thing a duel game can do is prove it. Arm the round, then watch: the two pads light from a single moment in the same frame, and the stamps below come from the browser's own clock. Tap a pad before the light and you will see the false-start rule instead — nobody's reaction is being timed here, and nothing is scored.
Press arm. The wait is drawn fresh each time, somewhere between one and four seconds, so neither side can learn the rhythm and count themselves in.
One signal, two pads, no opponent required and nothing kept — this bench only proves the timing is even. Tapclash is the rest of it: five modes, single rounds or a best-of match, and somebody on the other side of the phone to be wrong about who won.
