Ninja Battle Idle

Ninja Battle Idle is an upgrade kind of game in which Ninja fights itself. All you got to do is upgrade and just keep upgrading whenever you have enough coins.

Little heroes play this tiny ninja who chops up monsters relentlessly again and again. It gives you fun with two buttons: clicking your mouse deals damage, or just waiting (idling) earns gold automatically! Your hero gets stronger over time through getting upgrades from that gold. Soon it can use bigger swords or magic potions to hit harder or faster as more minions show up.

You buy things like better weapons or attacks using all the gold earned fighting monsters again and again. Each purchase makes your tiny hero stronger, ready for tougher challenges with badder enemies popping out constantly. The game feels satisfying because winning little bits early means you can build huge amounts later on – it’s easy to play but progress seems to blow up quickly thanks to these bonuses.

This basic game started way back in 2014 and players still seem to enjoy the simple clicking action, even if others find there are not many fancy new twists or ideas beyond what they originally did.
