MATTIS
Play Mattis, the classic Norwegian card game of strategy and risk. Free on iOS and Android with online multiplayer, solo AI, War, and fast tactical rounds.
How to play MATTIS
Master the two-phase system that makes MATTIS a Norwegian classic. One phase to build, one phase to win.
Phase 1: Collection
In MATTIS, the first phase is all about the build-up. You aren't trying to get rid of cards yet—you're building the hand you'll use to win later.
Players lay cards one by one. The highest rank "owns" the pile until someone beats it. If you match a rank already on the table, you trigger a "War" where the winner takes everything.
