Addition Adventure
Coming laterAddition Adventure carries addition and subtraction across seven worlds, each guarded by its own animated boss. Subtraction is taught as the flip side of the same addition facts, so the two build together instead of separately. Practice adapts to what's already known, bringing back facts that need more work until they're solid. Clear all seven worlds and a golden late-game era opens, with fully animated guardians waiting to be challenged. Addition Adventure isn't on the App Store yet, but the full seven-world journey is built and playable.
Seven Animated Guardians
Every world ends in a boss fight, and all seven guardians now have full animated encounters.
Addition Meets Subtraction
Subtraction is taught as the flip side of addition, so the two facts reinforce each other.
A Golden Endgame
Clearing the map unlocks a golden late-game era with its own animated guardian rematches.
Adapts To The Learner
Facts already known move quickly; facts still being learned come back more often.
