2Pow is a good but very difficult game.
Installation
The game is managed by haikuports and can be installed via HaikuDepot as normal. Unfortunately there was no 64bit version at the time of this tutorial.
Gameplay The aim of the game is to reach the binary number 2048.
To do this, you slide the numbers at stake back and forth with the help of the arrow keys.
If the same numbers come together, they are added together. 4 and 4 become 8, 8 and 8 become 16, 16 and 16 become 32 ... ... 1024 and 1024 become 2048.
If you cannot create new numbers, the game is lost.
