Immortal Chess

CHESS WITH MAGIC Immortal Chess keeps the strategy and rules of classic chess, then expands every match with classes, Mana, spells, traps and unique abilities. Every chess move grants Mana, giving you the power to transform pieces, control the board, disrupt your opponent and create positions that could never exist in ordinary chess. CHOOSE YOUR CLASS Play as one of nine distinct classes: • Inquisitor • Champion • Sentinel • Disruptor • Cultist • Monarch • Strider • Necromancer • Mage Each class offers its own spells, passive ability, strengths and playstyle. Classes are alternatives, not upgrades—victory still depends on strategy, timing and how well you use the board. EVERY MATCH PLAYS DIFFERENTLY Spells expand chess rather than replace it. Familiar openings can evolve into entirely new positions, while every move forces you to balance traditional chess strategy against Mana, abilities and threats. PLAY YOUR WAY • Compete in ranked online matches • Play across supported PC and mobile platforms • Practice against AI opponents • Experiment with different classes and strategies • Climb the global leaderboard • Customize your game with cosmetic boards and pieces FAIR COMPETITION Immortal Chess is free to play. You start with one free class and enough Essence to unlock at least one more class of your choice, or two lower-cost classes. This means you can begin with multiple playstyles and find the ones that suit you best. Additional classes can be unlocked with Essence earned by playing or purchased in the shop. Classes are different playstyles, not upgrades, and purchases never increase spell strength or provide direct competitive advantages.
