Tri-Ominos version with the hourglass.
Players are laying tiles that match up to other tiles in the play area, with the goal to get points and be rid of their tiles.
In Triominos Challenge, a special rule applies: if a player has not finished his turn in the time allotted by the hourglass, he draws an additional Triominos and scores -15 penalty points.
