FAQ

How do you play?

Tap two adjacent numbers to swap them. Win when they read in ascending order from left to right (1, 2, 3…).

What's the fewest number of moves?

The number of pairs where the left number is larger (the inversion count). Each swap changes the inversion count by exactly one, up or down, so making only swaps that reduce it gives the minimum. It's the same as bubble sort.

How do I play with a keyboard?

Tap a number to select it, then tap its neighbor. Or pick a number with the left and right arrow keys and press Space to swap it with the number on its right.

How is the leaderboard ranked?

By fewest moves, then by time. You only need a nickname, and you can submit up to 30 times a day per count. The server checks your moves.
