Noah and I had a go at a couple rounds of Rumis. In Rumis you take turns placing colored Tetris/Blokus shaped pieces onto a grid. The grid and height restrictions are defined by the chosen playing board. The only rules are 1) when you lay your piece, your piece must touch faces with at least one of your already positioned pieces and 2) you cannot create a hole or gap such that you can’t fill it by dropping a block vertically onto the structure. The winner is the player who covers the most top surface area. So at the end of the game, you have to look directly down onto the structure and count blocks of each color.
Rumis is a great game for winding up the evening and it’s easy to get several quick games in.
