30 Rails is a free print-and-play roll-and-write game played on a 6×6 grid. Players draw mountains a mine and stations and then fill in the remainder of the grid with track based on the outcome of die rolls.
Blankout is a free roll and write game in which players try to fill up a grid with tetomino shapes. A roll of a die determines which shape players must use, but the shapes can be rotated to fit on the grid. The last player who can still fit a piece in, tetris-like, is the winner.
