Every dig shows a number with one digit highlighted. Name its true value, its place, or the number's expanded form to strike gold and sail on!
Pick your starting grade:
Tap the correct answer (or press 1–4). Correct digs fill your ship with gold and build your streak. Miss or run out of time and a rival pirate creeps closer down the trail — get caught and it's game over. The game learns your weak spots (ones, tens, hundreds, tenths...) and digs up more practice right where you need it. 🏴☠️
