Play Mario Tower Online
Bowser's goons rush the castle while you scramble to set up turrets, drop mines, and juggle upgrades between waves—chaos gets wild when the screen's packed with bullet-sponge Koopas.

Mario Tower is one of those old-school Flash games that somehow still holds up. Bowser’s gone full crime lord—he’s emptied the bank, and now his goons are storming the castle while Mario’s nowhere in sight. You’re stuck holding the line with whatever weapons you can scrape together.
At first, you’re just popping off shots with a basic pistol, but after a few waves, you start dropping mines, setting up turrets, and even grabbing a flamethrower if you’re lucky. The controls are simple—mouse to aim, number keys to swap guns—but the real trick is managing your cash between rounds. Do you upgrade your firepower now, or save up for something ridiculous later? (Spoiler: go for the ridiculous option.)
It’s chaotic in the best way, especially when the screen fills up with bullet-sponge Koopas and you’re scrambling to reload. Princess Peach better appreciate this.
