Sharp Eye vs Duko

Same shape, same color — or is it? Sharp Eye is a visual matching game that starts simple and quietly becomes a memory gauntlet. Pairs of shapes appear inside semi-transparent squares. Instant decision: are they the same in both shape and color? Decide fast — the clock is running. Then the twist kicks in: after every answer the figures slide left and start vanishing. The further you go, the less you see — and the more you must remember. When only one figure remains on screen, that's where the real challenge begins. HOW TO PLAY • Judge each pair: same shape AND color — yes or no • Answer before time runs out • Figures slide off one by one as you play • Recall what you already saw when the screen empties WHY YOU'LL LOVE IT • One decision per second — instant to learn, tough to master • Combines visual matching with short-term memory in one loop • Difficulty rises with every correct answer • Blazing quick rounds — focus training in under a minute • Clean, minimal look with zero distractions A WORKOUT IN ATTENTION TO DETAIL Judging sameness trains selective attention and visual discrimination — the skills behind proofreading, quality checks and noticing what others miss. The vanishing-figure twist adds working memory on top. Two workouts, one game. WHO IS IT FOR? Fans of spot-the-difference, matching puzzles, reaction and focus games. Kids sharpening their eye, adults and seniors training theirs. The screen is fading — how far can you go? Download free and find out!

Whether you're new to sudoku or you've solved thousands of grids before, Duko's growing collection of themes and sizes gives you a reason to keep coming back. Start simple with numbers, then go as deep as 12x12 hieroglyphs whenever you're ready for the next challenge.
