GOT IT


GOT IT is an adding game for two. You can play against the computer or with a friend.

Start with the GOT IT target $23$.

The first player chooses a whole number from $1$ to $4$.

Players take turns to add a whole number from $1$ to $4$ to the running total.

The player who hits the target of $23$ wins the game.

To change the game, choose a new GOT IT! target or a new range of numbers to add on.
