Keep one of the piles clear as much as possible. Don't allow a pile of three cards to build up on top of a single card, especially if the final card from the set is not a bottom card in another pile.
Pila bat hutsik eduki ahalik eta luzaroen. Ez jarri hiru kartako pila bat bakarrik dagoen karta baten gainean, batez ere, multzoko azkeneko karta beste pila bateko beheko karta ez bada.
