Bibinary is a game in which you must find the binary code of numbers. It's almost fun. There is several levels, from A1 to F6. To pass a level, you must find 3 codes. There is two modes : the time mode and the infinite mode. In the time mode, you have a limited time (40s) to find as many binary codes as possible. You can start at the level you want (from the lowest level to the highest already reached level). In the infinite mode, you always start at the lowest level and you must go as far as possible. You win when you pass F6. In both modes, the highest reached level appears on the home page.

Swipe. Merge. Clear the board. Sudoku Zero is a number merge puzzle and brain teaser where every move matters. Swipe a tile onto its neighbor to merge them, then clear every number from the grid without getting stuck. A relaxing math and logic game that is easy to learn and hard to master. HOW TO PLAY 1. Swipe a block left, right, up or down onto a neighboring block to merge them. 2. Same numbers cancel out. Merge two blocks with the same number and both disappear. 3. Different numbers add up. Merge two blocks with different numbers and the swiped block disappears. The block you landed on becomes the sum of the two. 4. Mind the gaps. Blocks can only merge when they are next to each other.
