Kevin HY Hau - Hello World 👋

How to play: a colour is shown in the box. The grid is full of shades that look almost the same, and exactly one square is that colour. Tap it. Each find adds 5 seconds (the clock never goes above 100) and the next round gets harder: the shades get closer. A wrong tap costs time (you can change that in the settings). Pick the grid size: 12×12, 10×10, 8×8 or 6×6 (bigger = more to search, smaller = easier). Odd one out mode has no target: every square is the same colour except one that is slightly different. Your best score is saved for each grid size and mode. At the end the missed square is ringed so you can see it.
