A tiny defense game for the corner of your screen

Tiny Ring Defense runs in a small transparent window on your desktop. Monsters march around a ring that circles your board, and the heroes inside fight them automatically. Keep working, studying or watching videos while the battle goes on, and glance over now and then to spend the coins you have earned.

Summon, merge, level up

Spend coins to summon heroes onto the board. Each summon brings one of five classes in one of three grades: Common, Rare or Epic (1%) — or, very rarely (0.1%), a classless Mythic hero who can wield any weapon. Drag a hero onto another of the same kind to merge them, or feed a lower-grade hero to a higher-grade one of the same class. Before you let go, a preview shows how much the hero will grow, up to 5 stars. Level up each hero with coins, up to Lv 100.

Draw and forge weapons

Draw weapons with in-game coins in four rarities: Common, Rare, Epic and Legendary. Give each hero a weapon for its class and forge it up to +25. The higher you forge, the lower the success chance, and a failed forge destroys the weapon. There are no real-money purchases.

Six worlds, each with a twist

Meadow, Desert, Swamp, Snowfield, Graveyard and Volcano each bring six new monsters and their own music. Every world changes the fight: fast monsters, tough ones, swarms that shrug off slows, ghosts that dodge ranged attacks and armored foes. After World 6 the worlds come around again with stronger monsters.

Bosses on the clock

Each stage ends with a boss that walks one lap of the ring. Defeat it before it finishes the lap, or it escapes and comes back later. Turn off auto-boss to keep farming a stage, then call the boss when you are ready. World bosses arrive with escorts.

No game over

If 100 monsters pile up on the ring, you drop back one stage and keep earning.
