The guide

Overview

Challenge your speed and accuracy with One Plus Two is Three, an electrifying math puzzle game. Face escalating challenges under a ticking timer, testing your arithmetic skills and reflexes. Stay sharp, stay quick,each solution is a race against time, blending learning with adrenaline-pumping fun.

Short stages, soft landings, and a character a child can steer themselves. That is the shape of most junior games. There is more to do than in toddler games: a path to follow, a few obstacles, a simple puzzle or counting task. But nothing moves faster than a child can react, and a mistake just means trying again. Sessions end when the stage does or when attention does.

How to play

1Tap Play and watch the brief introduction, which shows the character and the one or two actions available.
2Steer with the arrow keys or on-screen pad, and tap or press space to jump or interact.
3Follow the path and collect what the game highlights. Dodge anything that moves toward you.
4Press next at the end of a stage, or replay to collect anything you missed.
