Viro Plain is a calm two stage game session built around quick color recognition on a grid. In the first stage, a 3×3 field shows tiles of different colors. A target color appears, and the task is to touch the matching tile before time runs out. Correct choices add points, and incorrect choices reduce the score, so accuracy matters as much as speed.
After reaching the stage goal, the second stage expands the grid to 4×4 and keeps the pace higher. The same core rule applies: match the shown color and keep the score stable while the timer counts down. At the end of the run, the result is summarized and saved on the device in a local record table.
