Also free for Android, Nambers, aside from being the sort of name that's really fun to mash around in your mouth, is a puzzle game by Oleg Kuzyk that's all about numbers and blocks. The idea is that each number indicates how many adjacent cells with that same number must be linked together in a single line (horizontally, vertically, or diagonally) without crossing over any other lines. Click on one cell and drag to create a path through cells, and, once they're linked, you can actually raise or lower their value by clicking on one of them and dragging to the right or left. Remember that a cell can only be successfully and changed if you have the proper numbers of cells linked... so if you're working with a two, you can't only manipulate one, or more than two. Sound confusing? It's actually easier in practice than it is to explain. Your goal is to make each level's grid match the one shown at the bottom of the screen, and do so in a limited number of moves to get all three stars. Click the arrow in the bottom-right corner to undo your last move. Though initially a little awkward to pick up, once you do, Nambers is a surprisingly stylish, clean little puzzle game that makes for some satisfying brain work, with more levels to be found on the mobile version.
