Rainbow Keno

Rainbow Keno by Caleta is a keno-style video game that blends traditional lottery mechanics with a colorful Irish-myth theme. The game uses an 80-ball draw, from which 20 balls are randomly pulled, and players choose between 1 and 15 numbers hoping to match as many as possible. The visuals include rainbows, a friendly leprechaun guide, and vibrant green landscapes to evoke the luck of the Irish. A core feature is the “Lucky Numbers” element: each standard round designates three special balls; matching all three triggers the standout bonus called Rainboways Bonus. In the Rainboways Bonus, players pick one color of the rainbow and watch the leprechaun slide down that path, gathering multipliers along the way. These multipliers can boost the total wager up to a very large maximum win. The game includes a Fast Pick option to auto-select your numbers, and also offers an Autoplay feature to run rounds continuously. Technology-wise, the game runs on HTML5, making it playable across desktop and mobile platforms. There is no free spins feature or traditional wild/scatter symbols; the bonus mechanics revolve entirely around the lottery draw and the multiplier-based Rainboways event.

You can try it for free in demo mode or play it for real money.
