A little scientist at play.
Designed with eight-year-olds in mind: big picture choices, short prompts and a helpful nudge when it is time to look at the evidence.
The puzzles get trickier. Some choices change several things at once, so players must work out what really made the difference.
The Android game runs on phones and tablets with Android 8 or later. The game is in English. All 22 puzzles are included, with no sign-in, subscriptions or in-game purchases. Progress stays on the current device.
