Gigamic Pylos (Nordic + EN)

In Pylos, you want to be the one to place the last ball at the top of the pyramid. Sounds simple enough, right?

At the start of the game, each player has fifteen marbles, either light or dark, and they take turns placing them on a sixteen-well game board in a 4x4 grid shape. When four balls are placed next to each other in a square, a ball can be placed on top of them, forming another game level. Players can then place marbles on this second level, which eventually allows a marble to be placed on the third level. When that level is full, requiring only four balls, a final ball can be placed on the fourth level and that player wins the game.
