Two Thrones
Read full descriptionHide 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.

Verdict
The clearest difference is in-app purchases: Two Thrones at none against Grid Guardians's 10. Grid Guardians's advantage is ads (none vs shown) and update cadence (weekly vs monthly). On price, device support and iOS requirement there is nothing between them.
