IBM’s Hello Quantum is now available on Android. If you only like easy puzzle games that don’t explain anything about how quantum computers work, you’re going to hate it.

The game, which debuted on iOS last month, was designed by University of Basel physics professor James Wootton and members of IBM’s quantum computing team. It plays like a combination of Go and Sudoku. And, like all good puzzle games, it’s pretty easy to understand at first but becomes devilishly complex as levels go on.
