Columbus Deluxe™ by Greentube is a 5-reel slot with 10 fixed paylines and a 95.02% RTP. The game uses a nautical treasure-hunt theme, with card symbols joined by explorer imagery, jewellery, ships, and Scatter icons that support the bonus features.
The demo version is available near the game launcher, allowing players to play for free and practice before playing for real money. The slot includes a Free Games round triggered by Scatter symbols, with the feature shown as 10 free spins in the provided material, plus retrigger potential during the bonus.
Another option is the Gamble, or double-or-nothing, feature, where a win can be risked on red or black to try for a higher amount. Betting ranges from 0.02 to 200, and the payline display is presented clearly in the interface for reference during play.
