Each turn, one player selects a building block, while the other decides where to place it in the grid. The first player starts by revealing a building block and choosing which two adjacent sides will be available for scoring. The other player then picks one of those sides and places the block, ensuring it’s adjacent to previously placed blocks. Players take turns choosing and placing blocks, working to strategically align scoring elements on their side of the building while restricting their opponent's options.
The game ends when all 15 blocks are placed. Players tally points for each block on their side of the building. The player with the highest score wins.
