Octocube

Under the sea, playful octopuses compete in dexterity to collect objects carelessly abandoned by their neighbors above.

On your turn, roll your cube/octopus onto an adjacent stack of tiles. The top tile will stick to the cube via magnetism.
When you choose (ideally after several rotations to maximize the cube's capacity), retrieve your cube to unload its tiles before placing it back into play.
Arrange the collected tiles on your personal board.
The player who scores the most points through majorities (objects, colors) wins the game.
