X nimmt! (A sequel to 6 nimmt!, with a more strategic twist)
2-4p / 8^ / 25-40m

Gameplay is roughly the same as in 6 nimmt!, with the following differences:
The cards run from 1-100, and players start with 8 of them.

There are only 3 piles – one is taken by the third card, one by the fourth,
and one by the fifth. When a player takes a pile, the cards are not taken
to be kept, but instead go into the player’s hand – however, they first
choose one of the taken cards and add it to their “X-pile” (cards in an
X-pile do not score). If the card is not higher than the last card added
to their X-pile, the cards already in the X-pile are moved to their
double-scoring area – those cards will score twice their usual value.

A round ends when a player cannot play a card (their hand is empty).
The other players score the cards in their hand and (2x) the cards
in their double-scoring pile, but not their X-pile cards (as mentioned).

After 2 rounds, the player with the lowest total score wins.
