Keno Games
Legend traces keno to Han-dynasty China, where a number draw allegedly funded city defenses and, later, stretches of the Great Wall. Chinese railroad workers carried the game to America in the 1800s, and it has lived in casino lounges ever since — one of the oldest gambling formats still in active play.
The modern online version keeps the ancient core: choose your spots, set your stake, and watch twenty numbers tumble out. Payouts scale with how many picks land, which makes paytable differences between variants matter more than they first appear.
SlotRanker lists keno games with RTP data side by side, so you can spot the generous paytables before betting. Every variant is playable in free demo mode.
