Gobblet! is a leveled up version of Gobblet Gobblers which is a leveled up version of Tic-Tac-Toe.
 

There are two main differences between Gobblet! and Gobblet Gobblers.

The board is a 4x4 instead of a 3x3.

Your 3 sets of pieces come in 4 sizes instead of 3.

There are just a few rules to the game.

Like Tic-Tac-Toe you can pick a space and take it with a gobblet.

But you may also place a larger gobblet on top of a smaller goblet.

Next, you can move a gobblet already on the field to gobble another gobblet or to an empty space.

Lastly, once you touch a gobblet, you must move the gobblet.
