Students answer questions correctly to collect treasure from the bottom of the ocean floor. Each piece of treasure is worth different amounts of points, depending on its size and colour. With every correct answer, students haul up more treasure—who will collect the most by the end of the game?

In this version, students solve an assortment of addition sums with totals up to 20. This helps develop fluency with number facts, supports early mental strategies, and builds confidence with simple addition through repeated, game-based practise.
