Overview
Itazura Daisuki! Sushimaru Kun (いたずらだいすき！スシマルくん) is a rare Japanese casino arcade game released in 1997 by Sigma. The title translates roughly to "I Love Pranks! Sushimaru-kun." It runs on Sigma's B-98 hardware and falls under the medal game / casino genre rather than a traditional arcade action game.
The game centers around a betting mechanic. You pick one of three bizarre or improbable customers seated at your counter.
You bet on whether you can successfully trick or surprise that specific customer—often by sneaking a massive dollop of extra-spicy wasabi into their sushi order.
The machine pays out tokens or medals depending on whether your prank succeeds or fails against the chosen character.
