PrimeLink is a free online match-3 puzzle game that challenges your math brain by making prime numbers the star of every move. Instead of matching colored gems or shapes, you link three or more identical prime numbers in a chain to clear them from the board. The longer your chain, the bigger your score multiplier — so thinking ahead pays off fast.

What makes PrimeLink genuinely tricky is the pace. The board fills up quickly, forcing you to balance speed with strategy. Early levels ease you in with smaller primes like 2, 3, and 5, but as you progress, larger and less familiar primes start showing up, demanding sharper pattern recognition and quicker decisions. Combo bonuses reward aggressive chaining, so hunting for long sequences rather than quick clears is almost always the smarter play. It's the kind of puzzle game that feels simple for the first 60 seconds and then completely grabs your attention.

PrimeLink is perfect for students looking for a fun way to get comfortable with prime numbers, puzzle fans who want something more mentally engaging than a standard match-3, and anyone who enjoys number games or logic puzzles online. If you search for free math puzzle games, prime number games for kids, educational match-3 games, or Halloween math games, PrimeLink delivers a genuinely satisfying challenge that sharpens number sense while keeping you hooked round after round.
