Ditto with Snakes and Ladders and the Goose game (juego de la oca in Spanish), with a similar gameplay. And Yahtzee.
With Oca/Snakes and Ladders and such, the outcome it's the same with 0, 1 and N players. You just throw a dice and watch the events.
Because even a paper and pen racing game with vectors can be more fun than Oca without any special slots to fall into.
