Drop blocks made of primes and divide every number on the board down to 1.
Prime Press is a prime factorization puzzle. Each cell of a block carries a prime and divides the number under it when it can; a number that reaches 1 clears. But the ringed "core" cell must divide the number under it, every time.
Features
100 studiesClear the board with the blocks you're given. Boards grow from 4×4 to 7×7, and primes join one at a time, from 2 and 3 up to 97. Every study is solvable.
Endless modeEnergy keeps draining; landing blocks restores it. The further you go, the larger the primes and the board, with numbers growing toward a billion.
Cores and foulsDrop a core where it can't divide and it's a foul. In studies the block comes back to your hand; in Endless your hands are tied for a moment.
