About

Two Thrones

Read full description

Two thrones, one battlefield. Two Thrones is a real-time battle game fought on a single lane between two facing thrones. Summon units, push the front line, and bring down the enemy throne within 4 minutes. When time runs out, sudden death begins — the first hit on a throne wins. ■ 4-minute matches, dense real-time combat - Ground units form a front line on a single lane; flying units pass over it - Skip anti-air and the sky breaks you; stack anti-air and the ground caves in - Thrones fight back, striking enemies in range with magic bolts - Your king rises from the throne to cheer, buffing your whole army ■ A 6-card deck, chess-like unit control - Pick 6 from 20 units (Common, Elite, Hero) — save up to 3 decks - Only one of each unit on the field. It must fall before you redeploy — every piece matters - One Hero per deck: Knight King, Shadow Reaper, or Dragon Lord - Bank mana for one big push, or bleed your opponent with cheap trades ■ Skills are cast by hand - All 20 units carry a unique skill — the timing is entirely yours - Piercing snipe, meteor, taunt, shadow-step assassination, carpet of flame... - The same deck plays a completely different game in different hands ■ Winning doesn't make you stronger. It makes you wider - Earn gold from victories and daily rewards to unlock new units - No stat advantages, ever — the same unit performs identically for everyone - No card levels, no random boxes. Unlocks only widen your options - No in-app purchases. There is nothing in this game money can buy ■ The daily loop - Daily login rewards and 3 rotating daily missions - Ranked trophies — win to climb, lose to fall - New player protection: early defeats cost you no trophies ■ Easy to start - Jump in as a guest — no sign-up required - Link email or Google to keep your account safe (optional) - A 5-step tutorial teaches the rules in live combat - 5 rotating battlefield backdrops (plains, snow, desert, misty forest, volcano) - Korean, English, Japanese / landscape only Cartoon-style fantasy combat — no graphic violence. New units and content are on the way. Take your throne. The other one is yours to break.
