Scratch: Prime Clicker

when Sprite1 clicked change [clickCount v] by [1] set [reward v] to (getLPF (clickCount)) change [PE v] by (reward) if (reward) = (clickCount) then // clicked on a prime if (clickCount) is not in [primesDiscovered v] then add (clickCount) to [primesDiscovered v] change [PE v] by ((10) * (clickCount)) end end

Moreover, the Scratch implementation makes the game modifiable by learners themselves. A student who plays Scratch Prime Clicker can later open the code, see the factorization algorithm, and change it—turning a player into a designer. That transition, from consuming math to producing it, is the ultimate goal of educational game design. scratch prime clicker
