Tic-Tac-Toe
Classic single and two-player modes.
Test your mind with optical illusions. Flip cards to find pairs of classic illusions: impossible shapes, motion patterns, ambiguous figures, checkerboards, afterimages and more. It is a focused way to practice attention, recall and visual perception.
Challenging and Adult-Friendly
Clean design keeps the attention on the effect itself. Play at your own pace or try to beat your best time and move count.
Tip: After each match, briefly name the illusion type (for example, "Penrose triangle" or "cafe wall") to reinforce learning.
