One tile is slightly off. Can you spot it? Play Endless, Daily Challenge, and Zen with three days of full access—no ads and no subscription.
Spotle is a fast color vision puzzle game built around one simple challenge: spot the difference before time runs out.
A grid of colored tiles hides one tile with a slightly different shade. Find it, advance to a denser grid, and see how long your focus and visual perception can keep up. Easy to learn, increasingly difficult, and ideal for quick games.
THREE WAYS TO PLAY
• Vision Test — 20 rounds, each one a smaller color difference than the last. Your score is how many you found. Missing a round costs the round, never the run, so you always finish with a result worth comparing.
• Daily Challenge — 10 seeded rounds. Everyone plays the same puzzle, every day, and keeps a streak going.
• Zen — No timer and no round limit. Three lives, solve at your own pace.
CLIMB YOUR VISION RANK
Rank is set by the hardest round you have ever solved, so it means the same thing in every mode: Rookie Retina, Sharp Sight, Keen Eye, Hawk Vision, Eagle Eye, and Color Oracle. Track your best test, deepest round, streak, and games played.
BUILT ON REAL COLOR SCIENCE
Rounds are generated in the Oklab perceptual color space, so a given round is equally hard on every hue instead of depending on which color came up. The difference is carried by lightness, which keeps the test fair for players with color vision deficiency.
STUCK? TAKE A PEEK
A few peeks per run briefly boost the difference. Spend one on a round you cannot crack, or save it for a harder one later.
THREE FREE GAMES
Your first three games are free, with no countdown running in the background. Play them today or next month. No energy, no waiting, and no ads.
KEEP SPOTLE FOREVER
After your third game, one optional non-consumable purchase permanently unlocks unlimited play, every mode, every theme, and complete stats. No subscription and no automatic charge. Existing Spotle Pro purchasers keep full access.
