2048 is a popular single-player game for Web and mobile. It’s a type of “sliding block puzzle” — think Threes!, on which 2048 is based, or the old-timey game klotski — that’s played on an almost Sudoku-like grid. Like Sudoku, it also involves some math. The object of the game is to combine the numbers displayed on the tiles until you reach 2048.

HEXTRIS is a fast paced puzzle game inspired by Tetris. Blocks start on the edges of the screen, and fall towards the inner blue hexagon. The objective of the game is to prevent the blocks from stacking outside the area of the grey hexagon. To do this, you must rotate the hexagon to manage different stacks of blocks on each face.
