Place every die lower than its neighbours - 91 handcrafted logic puzzles.
A quiet logic puzzle about placing dice in the right order. One rule carries the whole game: a die must touch a die you already placed, and its value has to be lower than or equal to every neighbour it touches. The first die is always a six and goes anywhere - from there, every placement narrows what is still possible.
The game is free and shows an occasional full-screen ad between levels, never during one.
