Gentle Gimmick Games Turns Ad Math Into A Bullet-Hell Shooter
The ad-gate gag is only the hook; the real design is a shooter where reading each equation, not reflex alone, decides whether your ship survives the next wave.

At OSAKA INDIE GAMES SUMMIT 2026 on October 3 and 4, Gentle Gimmick Games showed MAaaaaTH!, a bullet-hell shooter built on the arithmetic gates seen in mobile game ads. Gates carry expressions like X+log10(8) and B times the square root of 8. The four variables A, B, X, and Y determine life, movement speed, attack power, and other stats through equations, so a larger value does not always mean a stronger ship.
The premise came from frustration: the developer says the trigger was game ads that keep getting simple arithmetic wrong. In the game, the Math God hears a wish to never see those ads again, misreads it, and traps humanity in a prison of arithmetic. Stages put gates on screen, but the labels are expressions you cannot judge at a glance, and enemy bullets keep coming while you decide.
Stats are not bought with flat upgrades. Clearing a stage earns Quartz, and equipping them into a weapon's four slots rewrites the equations themselves. Quartz carry math names, including Epsilon-Delta, Zeta Function, Sequence, Vector, and Origin Point, with system names such as Fibonacci Systems and Riemann Analytics. Enemies and bosses follow the same logic, appearing as asteroids, cardioids, and trefoil knots.
