Idle Hero Arena

Idle Hero Arena is a laid-back idle auto-battler RPG. Build a team of cartoon fantasy heroes, position them on a 3x3 battle grid, and watch them fight on their own. Your job is to set up the formation and grow stronger — the heroes handle the swinging, casting, and shooting for you, wave after wave, all the way up to the ice dragon boss.
Every stage throws waves of enemies at your lineup. Survive each wave to advance, and when the boss appears, your whole team focuses fire while damage numbers fly across the arena. A live damage ranking shows which hero is carrying the fight, so you always know who to upgrade next.
Because it is an idle game, progress keeps ticking even during short breaks. Come back, collect what your heroes earned, level them up, rearrange your formation, and push into the next dungeon. It is single-player and playable offline — no account and no internet needed to play.
HOW TO PLAY
Place your heroes onto the 3x3 grid to form your battle lineup.
Start the stage and let your heroes auto-attack the incoming enemies.
Clear each wave to move on to the next, tougher one.
Focus your team's damage on the boss (like the ice dragon) when it appears.
Check the damage ranking to see which hero deals the most.
Spend your earnings to level up heroes and strengthen the lineup.
Rearrange the formation to counter new enemies and clear the next stage.
Optional rewarded ads let you speed up your progress or claim extra bonuses — watching them is always your choice. Jump in, set your formation, and let your heroes carry you through the dungeon.
