Fat Brain Corners Up

The Fab Brain Corners Up is a game of strategically stacking game pieces to try and collect corners.
Each player gets 20 game pieces of one color. On each turn, players have to place one of their piece adjacent to or on top of the other pieces within a 4×4 grid, building a pyramid as they go.
When a 2×2 square is completed, whoever has the most pieces within that 2×2 square gets to place one of their pieces on top of those four.
The game continues until the last piece of the pyramid is placed. Then, start counting up the corners. – Whoever is occupying the most corners wins the game!
The game encourages fine motor skills development, spatial reasoning, strategy, critical thinking and problem-solving.
