Cube Lines
Four in a row on a 4x4x4 cube against six animal rivals. The four layers sit side by side, and lines can run straight through all of them, so the danger is often in the tray you were not watching.

About the game
Cube Lines is four in a row played inside a cube. The board has four layers of four by four cells, laid out side by side as four wooden trays. You and your rival take turns dropping blocks into any empty cell, and the first to complete a line of four wins.
The catch is that a line does not have to stay in one tray. It can climb straight through the same cell of every layer, or run diagonally from a corner of the first tray to the opposite corner of the last, so 36 of the 76 possible lines pass through all four layers. A small 3D cube on the rug shows those lines as straight rods. Over twenty-four levels you face six animal rivals, from a mouse that misses easy blocks to a panda that plans forced chains, and the glowing helper threads fade away as you climb.
