About 15 Puzzle - Collect numbers
We present to your attention the classic version of the game 15 Puzzle - Collect numbers. Exactly the way it was invented in 1878 by Noah Chapman. We have added only difficulty levels and an auto build feature. The assembly function is intended, first of all, to check the collectibility of the required combination of numbers, if you suddenly have doubts. There are no uncollectible combinations in our game.
How to play 15 Puzzle - Collect numbers
The opening minute doubles as the tutorial. The full control mapping is in the table below and takes a moment to skim. The game runs in portrait, so on a phone you can play one-handed, and on desktop it stays centred rather than stretched out of shape. Take the first run as practice and the second one seriously.
