Jissen Pachi-Slot Hisshouhou! 4

Jissen! Pachi-Slot Hisshōhō! 4 is a pachi-slot (Japanese slot machine) simulation game and part of Sammy's long-running series of gambling sims. It features a faithful recreation of three different real-life slot machines from two manufacturers: Cranky Condor by Universal, 50's by Sammy, and Aladdin Master X by Sammy.

The main game mode is the "Trial" mode, in which the player enters a custom gambling hall and must earn winnings on each machine inside it. There is also the "Simulation" mode which lets the player select any configuration of any of the three featured machines, and practice without any time or money limits. Both modes include detailed progression and stat tracking.
