About Rainbow Colour Drop

Rainbow Colour Drop is a bright, touch-first sorting game for toddlers aged two to four. Under a festival sky of floating clouds and rainbow bridges, colourful objects appear in a tray at the bottom of the screen, and the child drags each one into the bucket that matches its colour. Every bucket is clearly labelled and large enough for small fingers, and a gentle snap pulls each object neatly into place when it is dropped on the right target. Children who cannot yet drag can simply tap an object and then tap its bucket, which works the same way and keeps the game playable for every ability and for keyboard users. Correct drops bring a cheerful pop and a rainbow burst, while a wrong bucket gives a soft, friendly nudge and lets the child try again with no penalty. The game builds early skills that matter long before formal maths: sorting and classifying by a single attribute, naming colours, and matching like with like. Rainbow Colour Drop works in any modern browser, asks for no sign-up, never advertises to children, and stores progress only on the device. It pairs well with our colour and shape worksheets for hands-on reinforcement away from the screen.

A hand for grown-ups

Before you start
These need thinking time, not speed. Set the expectation that a good puzzle is meant to take a while.
While they work
Resist jumping in. A long pause is a child thinking, not a child stuck — give it room before offering a nudge.
Afterwards
Ask "how did you work that out?" more than "is it right?". The reasoning is the skill; the answer is just the evidence.
Watch out for
Guessing to escape the discomfort of not knowing. Reassure them that being stuck for a bit is normal and fine.
Away from the screen
Play strategy games, do puzzles, ask "what comes next?" with patterns of objects. Reasoning is a muscle.

How to play

  1. A question appears on screen

    A maths question is shown in large text at the centre of the play area. A timer bar begins counting down from 60 seconds.

  2. Choose the correct answer

    Answer options are shown as large buttons. Tap and drag, or use the mouse on desktop. Any input method works — touch, mouse or keyboard.

  3. Build your streak

    Each consecutive correct answer increases your streak. A longer streak lights up the flame icon and adds a bonus multiplier to the XP you earn for the level.

  4. Finish the level

    Each level has 4 questions. Complete them to earn the full level reward (+10 XP, plus up to +10 XP for a perfect run). Progress is saved locally and shown on the Parent Dashboard.
