MUC GAMES released the full version of the deck-building roguelite Slot & Dungeons on Steam on July 28, 2026. The game, which entered early access in October 2025, combines slot machine mechanics with dungeon exploration: spinning a slot at the start of each floor determines the placement of enemies, items, and other elements on a grid map. The 1.0 update adds a fourth playable character named Sinner, who specializes in status-effect attacks, and a new dungeon called Space, which features stronger enemies and new gimmicks. An Endless Mode lets players continue runs after clearing stages, and a ninth difficulty level has been added for existing stages. Other additions include a battle history viewer, a preset system for permanent upgrades, and over 150 items, 130 spells, 240 relics, and 200 enemy types. The regular price is 1,110 yen, but a launch sale drops it to 777 yen until August 11. Steam user reviews currently sit at "Very Positive" with 86% of 259 reviews positive, according to Automaton.
