Circles Color Reaction Game

One shape doesn't match. Find it. Tap it. Before the timer runs out.

Circles is a fast, minimal reaction game about spotting the odd one out. Every

wave fills the screen with matching shapes, except one. The difference starts

obvious and gets razor thin, wave after wave, until you're separating colors

your eyes can barely tell apart.

HOW TO PLAY

- A pattern of shapes appears

- One of them is different

- Tap it before the timer empties

- Every correct tap makes the next wave harder

TWO WAYS TO PLAY

Endless. Keep going as long as your eyes and reflexes hold out. No finish

line, just your next best score.

Daily Challenge. 20 waves, identical for every player, every day. Clear them

all for a bonus and build your daily streak.

IT'S NEVER THE SAME TWICE

The odd one out isn't always a color. As you climb, waves start hiding it in

new ways:

- Color - the classic, and it gets brutally subtle

- Shape - one square hiding among circles

- Size - barely bigger, barely smaller

- Rotation - one tilted the wrong way

- Inverted - now tap the matching ones instead

- Pulse - everything breathing at once

Shapes arrange into rings, grids, spirals, arcs and scatters, then start

drifting, swaying and orbiting the deeper you go.
