MIRAGE is a two-choice game where you pick the objectively correct option while your eyes are being fooled. Ebbinghaus (size), Müller-Lyer (length), simultaneous contrast (darkness), plus count, area and vertical-horizontal illusions appear at random — if your brain loses to the illusion, you're wrong.
There's always a real answer (one really is bigger / longer / darker), but context warps your perception. You're fighting the gap between what you see and what is true. Each round shrinks the real difference, strengthens the illusion and cuts the time limit. It's language-free, so anyone worldwide can compete.
▶ MIRAGE — Play free nowEach round shrinks the real difference from 30% down to 3.5%, strengthens the illusion, and cuts the timer from 4.2s to 1.8s. Obvious at first, but late rounds pit illusion against fact until intuition fails.
Aggregated from 20 personal-best records stored on MIKIRI's own servers (as of 2026-08-07; one record per player, flagged runs excluded). The sample is still small, so read this as where early players are stalling rather than a settled trend.
The median is ROUND 9. Only 25% of players get past ROUND 13 (advanced).

MIRAGE deliberately builds situations where the eye goes wrong, then asks what is actually there. Background motion, local contrast and apparent movement all pull against the correct answer.
Illusions do not go away once you know about them — you still see them. So the question here is not whether you can avoid being fooled, but whether you have a procedure for checking your first impression.
Judging the whole scene. Contrast illusions are strongest when you take in a wide area. Narrowing to just the two things you are comparing can reveal the difference.
Being dragged by the background. When the background moves, stationary objects appear to move too. Anchor your judgement to the screen edge.
Overthinking. Lives are limited: banking the next clear answer beats grinding on one you are unsure about.
