Pirate Fort turns math games for kids into a siege: the child stands on the wall of a colonial fortress as pirate ships appear on the horizon and send longboats to the beach. The cannon is loaded — but it fires only when a math problem is solved. A correct answer sends a cannonball arcing across the bay: ships splinter and sink, pirates are blasted off the sand.
A wrong answer means the enemy volley finds its mark — the fort loses a heart. 20 different ship types from dinghies to the Leviathan flagship, 30 different pirates with tricorns, hooks, parrots and peg legs. Hold the wall!
How to play
Read the problem at the bottom, tap the right answer — the cannon fires by itself at the biggest threat. Sink the ships before the pirates reach your wall!
What your child learns
Fast mental arithmetic under gentle pressure: addition and subtraction that grow with each level — every correct answer is a cannon shot, so counting practice feels like defending a fortress.
The science behind the games
Every Dad4Kids game is built on one simple truth: children want to play, not study — so we turn learning into a game worth replaying. The method draws on peer-reviewed research in game-based learning, motivation, and how memory works.
