An educational game for ages 8-12, Nautical Number Hunt teaches mathematics as Wanda Wavelet recovers treasures from the ocean. Treasures are placed along a number line, and your job is to move the sub above the treasures with the power of math. For example, when learning addition, you will add or subtract a number from the sub's current location to move. The goal is to acquire as many treasures as possible before the treasure beam runs out of power. 26 lessons are included, including lessons in finding numbers, estimating, addition, fractions, and even multiplication. Also included is an exploration mode and a two-player mode (the two players compete to bring back the most expensive treasures).
