The Curious Machine by Betsoft is a five-reel, 30-payline slot released in April 2015. The game uses a medium volatility model and a reported RTP of 97.50%, with wins paid from left to right across the reels. Players can open the demo version to play for free and practice before playing for real money.
The theme follows inventor Miles Bellhouse and his steam-powered robot, Gizmo, in a steampunk setting built around clocks, gauges, blueprints, machinery and a futuristic cityscape. Visible symbols include character portraits, workshop devices and technical designs. A Vortex Wild symbol can substitute in winning combinations, while the paytable lists different payouts for matching symbol groups.
The interface includes balance, bet and win counters, plus spin, autoplay, paytable and double-up controls. A bonus gamble screen asks players to choose Gizmo’s left or right hand to find the coin, with a warning about the bolt, creating a risk-and-reward feature tied to the game’s mechanical theme.
