To keep the tiles tidy and organized, I made this tiles box with a 10° incline so that they are easy to pickup.
There are 3 separate cover so it is not confusing when you play with or without expansions.
Of course when playing with expansions, you are supposed to remove all the tiles, mix them together and put them back. Keeping expansions 1 and 2 in the last rows are for storage or playing without them.
I really liked making this design and am working on making it parametric so that I can use it in all tile based games (Carcassonne, ...)
