BODY: A six-player co-op game about climbing a creepy casino tower to pay off a loan shark just became one of 2026's fastest-selling indie hits. Publisher TENSTACK announced on May 10 that Gamble With Your Friends, developed by TEAMGWYF, has crossed one million copies sold only one week after release.
The game bills itself as a "casino crawler" โ a mashup of dungeon-crawler progression and party-style gambling. Up to six players climb floor by floor through an unsettling tower of casinos, taking on rigged card tables, slot rooms, and bizarre house games. The catch: every group starts in debt, and the loan shark expects regular payments. Fall behind, and the tower's hospitality turns hostile.
Word of mouth has been driven largely by streamers, where the mix of nervous laughter, betrayal, and shared financial panic makes for ideal broadcast material. Clips of friend groups arguing over whether to pool winnings or skim from the pot have circulated widely on Japanese social media since launch.
TENSTACK has not yet shared a regional sales breakdown, but a significant chunk of early traction has come from Japan and East Asia, where co-op horror-comedy titles continue to dominate the indie charts.
The insider take
Japan's indie scene has been quietly converging on a very specific formula over the past two years: small player counts (4โ8), voice chat as a design pillar, and a horror-tinged aesthetic borrowed from late-night Showa-era pulp. Gamble With Your Friends fits that mold almost perfectly, and TENSTACK โ a publisher that has been steadily building a portfolio of "stream-shaped" multiplayer titles โ knew exactly what it had. The casino setting also taps into a uniquely Japanese fascination with the iconography of gambling (think Kaiji, Akagi) without requiring players to actually understand pachinko or mahjong. Expect a wave of imitators by autumn.
