About this game

Run, merge, and grow to become the largest number on the track! As a runner with a number on your head, touch another runner with the same number to merge. For example, 2 becomes 4, 4 becomes 8, and so on up to 2048 and beyond. Other numbers turn gray and roll off the track, so choose your lane carefully.

Navigate through x2 and x4 gates, avoid halving obstacles, jump off ramps onto the upper road filled with gems, and smash number walls that are smaller than you. The track features a variety of challenges, including saws, swinging hammers, spinners, spikes, narrow bridges, and road forks. New obstacles are introduced level by level and gradually combine with existing ones.

At the finish line, a giant boss awaits. Tap to unleash all the numbers you've collected. Bosses are tough: any damage you deal remains, so keep returning stronger until they fall. Defeat a boss to unlock a bonus level filled with gems and coins.

The game features 8 types of obstacles: saws, ramps, forks, number walls, hammers, narrow bridges, spinners, and spikes. Bosses accumulate damage across runs, and bonus levels with gems and coins are available after each boss. Upgrade your power and starting number, and collect 19 different hats, ranging from a party hat to a golden crown. The game is playable on both desktop and mobile, in both landscape and portrait orientations.

How to play

1. Tap to begin running.
2. Steer left and right into runners that carry YOUR number to merge with them and double it.
3. Pick the good gates, jump over ramps and avoid obstacles, since a hit cuts your number in half.
4. At the finish line, tap to shoot the boss. The damage you do is kept for your next attempt.
5. Spend gems on POWER (more damage), START (a higher starting number) and hats.
