In the quick, spatial, tactical dice game Omba, players try to block one another on the tiny game pitch, which measures only 3×3 squares. All pieces start off the pitch. On a turn, a player rolls the die and either moves a piece on the pitch or enters a piece onto the middle square of his side of the pitch. A piece must use the full die result, can move only orthogonally, and can't enter the same space twice on a move. Spaces with other pieces in them aren't off-limits, but the cost in die points to move into and out of such spaces equals one plus the altitude difference between the two spaces. When you end movement in a space with another piece, you place your piece on top of it, trapping it. Stacks can be of any height – but make sure you are able to leave again when you climb a stack! A player who cannot make a move is eliminated, but his pieces remain on the pitch. The last player who can move wins.
