Your Progression

From Curious to Master

Go from 0 to 1, and 1 to ∞.

Experience deterministic, tactical card combat. Every move matters.

Strategic setup is key. Position your cards across 4 columns and 2 ranks to form an impenetrable line.

Strike from your front rank. Watch damage cascade through columns and overcome your opponent's defense.

Rebuild your formation mid-battle. Deploy new cards to your back row as the front line shifts.

Your journey in Phalanx Duel has a clear path. Start simple, practice solo, then compete for rank.

Curious (0 → 1): Watch a match or play the Solo Bot (Easy). No pressure, just learn the flow.
Player (1 → 10): Play the Solo Bot (Medium) to test your defense. Then challenge a friend.
Master (10 → ∞): Compete in ranked play. Study suit boundaries. Use the Battle Calculator to find lethal lines others miss.

Players take turns. The game and each turn have phases, and the current phase determines whether you deploy cards or attack.
