ONE TOWER: Idle Tower Defense

ONE TOWER — one tower, endless waves, and a wall you will spend weeks climbing.

You start with almost nothing: Damage, Attack Speed and Health. Everything else is locked. Every wave you survive pushes the fog back — Critical hits, Range, Defense, Multishot, Missions, Research Labs, Events, Cards, Tournaments — until your tower is unrecognisable.

EVERYTHING UNLOCKS. SLOWLY.
• In-run upgrades open as you reach new waves.
• The Workshop starts with three permanent upgrades. The other twelve are unlocked one after another with coins.
• 10 Ultimate Weapons, each attuned with Power Stones — and every one costs more than the last.
• Enhancement Amps: 400 levels per track, and the price climbs forever.
• 20 tiers of difficulty. Each tier asks for more waves than the last — 60 at first, 200 at the top — and enemies that stay at your walls until you kill them.

A REASON TO COME BACK EVERY DAY
• Missions: three every 8 hours, paying gems and coins, plus a weekly chest.
• Tournaments every Wednesday and Saturday. Climb from Copper to Legend — the top 4 promote, the bottom 6 of Platinum and above drop.
• Two-week events: earn medals and unlock permanent Relics. Relics rotate and may never return.
• Daily challenges that rewrite the rules — Boss Rush, Coin Rain, Speed Rush and more.
• Wave milestones that pay gems, card chests and Power Stones.

GO DEEPER
• 14 collectible cards in 4 rarities, with extra slots to earn.
• Research Labs that keep running while you are away — up to 5 at once.
• Prestige for Cores, and spend them on permanent Research.
• Up to 8 hours of offline income.
