Mattis: Multiplayer Card Game

Expert AI & Online Play

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Level up your Mattis profile, keep a daily streak, and challenge Expert AI in fast 5-10 minute card rounds online or offline. Avoid being the last one standing in Mattis, the strategic card game that combines collection and shedding into a single tactical experience. Play online with friends, practice offline, and now build your profile with XP progression, daily streaks, and a tougher Expert AI challenge. HOW TO PLAY Mattis is played in two distinct phases that test foresight and adaptability. PHASE 1 - COLLECTION • Each round, play one card from your hand. • The highest card wins and collects all cards on the table. • Collect wisely - those cards become your lifeline in the next phase. PHASE 2 - SHEDDING • Empty your hand before everyone else. • Follow suit and beat the previous card to shed yours. • The last player holding cards becomes the Mattis and loses. MASTERY & PROGRESSION • Earn XP after games and level up your Mattis profile. • Keep a daily streak with fair rolling streak reminders. • Share your profile progress with friends. • Challenge Expert AI when you want a stronger solo opponent. UNIQUE MECHANICS • WAR: Tie on a play? Enter a sudden-death battle where only the strongest takes the pile. • CHANCE: Out of good cards? Draw blind from the deck for a high-risk, high-reward move. • BLOOD MATTIS: Collect nothing in Phase 1? Instant elimination. FEATURES • ONLINE & OFFLINE: Play anywhere, with or without internet. • SMART AI: Choose the difficulty that fits your round, including Expert. • QUICK SESSIONS: A complete game takes only 5-10 minutes. • GAME CENTER: Track achievements and leaderboard progress. • NO PAY-TO-WIN: Skill and strategy determine the winner.
