JajTur

JajTur is the simplest duel there is: two phones, one clock, and whoever shakes faster wins.

Pick a round — Easy (10 seconds), Hard (20) or Expert (30). The server counts you both in with a 3-2-1, opens one shared window for both phones at once, and you shake your phone up and down as fast as your arm allows. Your count climbs on your screen; your opponent's count climbs right next to it, live. When the clock runs out, the higher count takes the round.

WATCH THEIR BALLOON GROW
Your rival's score inflates a big red balloon on your screen, their name written across it. If they end the round ahead, it bursts in a splash — and if they are really fast it pops mid-round. Keep it small. Keep shaking.

FEEL THE PRESSURE
A tiny haptic tick confirms every counted shake, and the moment your rival overtakes you, your phone gives a full-second buzz — you will know without looking.

QUICK DUEL
Matchmaking pairs you with an opponent at your round length. If nobody is around, a practice stand-in steps in after a few seconds so you always get a race (stand-ins never appear on the leaderboard).

PRIVATE ROOM
Get a six-character code, read it to a friend, and settle it head to head. A private room is always another human.

SOLO VS BOT
Four offline opponents, from a gentle Rookie to a near-human Machine. No network needed — practice your technique anywhere.

FAIR, AND BUILT TO STAY THAT WAY
• The server owns the clock — both phones get exactly the same window.
• Counts stream to the server live during the round, never as one final number, and anything faster than a humanly possible shake rate (about 10 per second) simply does not count.
• Only real vertical shaking counts, and the phone has to be in your hand — a phone parked on a vibrating surface scores zero.
• The final score is computed on the server and revealed to both players together.
