About PlayMemorize Sequences

PlayMemorize Sequences is a free number pattern recognition game. You see a series of numbers and must figure out the pattern to predict what comes next. Patterns include arithmetic, geometric, Fibonacci, prime numbers, triangular numbers, factorials, and alternating series.

Progressive difficulty. Early rounds use simple arithmetic sequences (add 5, multiply by 3). As your streak grows, the game introduces Fibonacci patterns, power sequences, prime numbers, and eventually alternating and factorial sequences.

Learn as you play. After each answer, the game reveals the pattern type and its rule (e.g. "Fibonacci: a+b=c" or "Triangular: +1,+2,+3..."). This turns every round into a mini math lesson.
