2048-3D Infinity is one of many 2D and 3D 2048-like games.
A virtual 4x4x4 box contains numbered dices. You can swipe all dices to the top, bottom, left, right, front and back of the box. Two colliding dices with the same number N merge to form a new dice with number N+1. After each swipe a new dice with number 1 emerges on one of the free positions in the box. You can flip the 4x4x4 box by tapping on one of its six edges.
In theory you can create a 64 dice with this game. Unfortunately you need billions of years (do the math) to create such a dice. This is the perfect game to waste your time.
