Number Smash: 1 to 50 Game

Reflex test. Battle friends.

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Tap 1 to 50 in order. That is the whole rule of this number game, and it still falls apart around 20 — your eyes are hunting for the next number while your finger has already gone for the wrong one. Now play it with your friends. Up to six players share one board. Survive each round, and the last two meet in the final. It is a multiplayer number battle, a reaction time test and a brain training puzzle in one arcade game. Nothing to learn before you start — three seconds after you open it you are already playing. ■ PLAY WITH FRIENDS • Create a room and share the 6-digit code — 2 to 6 players, from a 1v1 to a full six. • Quick Match finds you opponents at your skill level, based on Elo. • Everyone plays the same board. • Each round is timed. When the clock runs out, the players who broke the fewest numbers that round are knocked out. • A live race track shows everyone's position. • Knocked out? You can keep watching until the end. • Wins raise your Elo, and the versus leaderboard ranks everyone by it. ■ HOW TO PLAY • Find the numbers 1 to 50 scattered on the board and break them in order. • There are six blocks, and each one breaks a different way. • Wood — one clean tap • Stone — hammer it with fast taps • Ceramic — press and hold until it gives • Vault — spin the dial until it opens • Cloth — cut it with one swipe • Link — join a run of numbers in a single stroke • You do not get to choose what comes next. You read it and you react. ■ FIVE SOLO BOARDS • Mix — all six blocks together, the default number puzzle • Wood — pure reaction time, nothing else • Vault — a test of finger accuracy • Cloth — the board where your swipe path decides the record • Link — the thinking board, where you read ahead • Every board keeps its own record and its own world ranking. ■ THE DAILY — THE SAME BOARD FOR EVERYONE Today's board is generated from today's date. Same numbers, same layout, same blocks, everywhere on earth. Clear it and see where you stand against the world today. A 30-day calendar marks every day you showed up. Tomorrow there is a new one. ■ THE RUN TO BEAT IS YESTERDAY'S Your best sets the pace, and you can watch it live while you play — ahead or behind, number by number. Runs are lost half a second at a time. ■ RANKINGS DECIDED BY 0.01s Every solo mode has its own global leaderboard. Near the top, whole seconds stop being the unit and hundredths decide it. ■ 107 ACHIEVEMENTS Boards played, blocks broken, finish times, daily streaks, versus wins and a few hidden ones. Some you trip over on the way through. Others you go hunting for. ■ FEATURES • Play real people — invite your friends, 2 to 6 per room • 1v1 or six-player elimination on the same board • A one-rule number game — no tutorial needed • Short rounds, made for killing time when you are bored • Six block types, so the reflex training never goes flat • Portrait and one-handed, so it works anywhere A multiplayer number game, a reaction time test and a brain training puzzle in one casual arcade game. Play with friends, challenge them 1v1, train your attention and your eyes. So how fast can you get from 1 to 50 — and can your friends get there first?
