Drehwürmchen

27 wooden disks show a little worm on one side, nine each of three colors. These are shuffled facedown on the table.
Players take turns rolling a die. When a player rolls a worm symbol, s/he can start flipping over disks (with one hand). Whenever s/he finds three of the same color, s/he takes them. However, the other players continue rolling in the meantime. Another worm means scoring: The active player may take a raspberry tile for each set s/he claimed, flips back and shuffles all tiles. If a raspberry is rolled, the player leaves the remaining open disks open and another player continues the flipping until a worm is rolled, etc.
When all raspberry tiles have been claimed, the player with most raspberries is the winner.
