Strategy guide
- 1.Start by flipping all cards once to memorize their positions before attempting to match pairs;
- 2.Focus on remembering at least 2-3 card positions at a time to systematically find matches;
- 3.Use the process of elimination by keeping track of already matched pairs to narrow down options.
Common mistakes
- 1.Randomly tapping cards without remembering positions, leading to repeated failed matches;
- 2.Focusing only on visible cards instead of memorizing flipped ones when searching for pairs;
- 3.Assuming cards remain in same positions after being flipped back, causing confusion in later attempts.
