You’ve barely recovered from sweating through the maniac shooter Armed Police Batrider in the previous challenge, and you think you can finally relax? Think again! The 7th One Credit Challenge throws you into Spinmaster — as cute as it is explosive!

Spinmaster is a colorful, adrenaline-packed run & jump developed by Data East in 1993 for the Neo·Geo MVS. You follow Johnny and Tom, two adventurers searching for a stolen artifact, in a cartoony atmosphere reminiscent of both Joe & Mac and 90s animated shows. The game stands out immediately thanks to its art direction: super-smooth animations, expressive characters, and richly detailed environments.

The gameplay focuses on ultra-dynamic action built around a customizable boomerang that can take several forms (yoyo, missiles, flames…). It’s easy to pick up and very accessible, yet surprisingly intense thanks to numerous special attacks and multi-phase boss battles. With its fast pace, zero downtime, and level design mixing platforms, waves of enemies, and little surprises, the game keeps players constantly on their toes.

In co-op, Spinmaster becomes even more chaotic and fun: combined attacks, screen-filling effects, and generous power-ups make it a fantastic pick for two-player arcade sessions. But for this challenge, you’ll have to score as high as possible solo. With its short but intense playtime, charming art style, and punchy gameplay, it remains one of the Neo·Geo’s must-play titles.
