In Keltis: Der Weg der Steine Mitbringspiel, a small standalone game in the Keltis family, the familiar idea of creating a numerical sequence is mixed with a press-your-luck element.

On a turn, you either take a tile from the center of the table and add it to your tableau or flip a face-down tile, then either leave it in place or add it to your tableau. Tiles come in five colors numbered 0-10, and when you place the second tile of a color, you lock in whether you're ascending or descending in that color. For example, if you take a blue 2, then a blue 4, you can place only blue 5-10 in the future. Some tiles have a symbol that grant you another turn immediately.

When the final tile is flipped, the game ends after that player finishes their turn. If you've collected only 1-2 tiles of a color, you lose points; the same applies if you collect fewer than two "wishing stones", a symbol scattered across multiple colors. Sum your score for all five colors and wishing stones, then add any bonus points on tiles you collected. Whoever has the highest score wins.
