Roobet Keno: pick numbers, five-ingredient verification

01Numbers, draws and hits

A Keno board shows a grid of numbers. The player marks some of them before the bet; the count of marked numbers is a choice, within the range the board allows. The game then draws a fixed quantity of numbers from the same grid. Every drawn number that matches a marked one is a hit, and the payout table on the panel converts the number of hits into a multiplier for the chosen number count. More marked numbers mean more possible hits, and the table shifts accordingly.

The in-game payout table is the only source of the multipliers; the operator does not publish house edge figures for its Originals and this guide does not estimate one. A player who wants to study the table can open Fun Play, mark different counts and read the multipliers without staking. The hub of the Originals describes how Keno differs from the tile games such as Mines.

• mark numbers on the board before the bet;
• the game draws a set of numbers from the same board;
• each match is a hit;
• the payout table maps hits to a multiplier for the chosen count;
• the draw is derived from the seeds, the nonce and the selections.

The Roobet guide opens with an overview of the catalogue, the cashier, the rewards and the licence; this chapter goes into one part of it in detail.

02A Keno round

The board and the payout table sit side by side on desktop and stack on a phone. Real bets need an account with a balance; Fun Play runs with play money. The game is for players of 18 and over, and the responsible gambling page describes the limits an account can set.

1. Open Keno in the Roobet Originals category.
2. Mark the numbers on the board, or use the random pick if the panel offers one.
3. Set the stake between one cent and $20,000.
4. Press Bet and watch the draw.
5. Read the hits and the multiplier from the payout table.
6. Open the round in the history to copy the seeds, the nonce and the selections.

Autobet repeats the same selections and stake for a series of draws.

03Limits for Keno

Keno falls under the general Originals limits of the Game Policy v4.5.0; the policy names no exception for it. The cap on a single win matters for the highest hit counts on a large stake.

Which bets feed rakeback is set out in the rewards chapter.

04Provably fair: five ingredients

Keno is the first Original on the fairness page whose ingredient list includes the player's own choices. The five items are: a round hash, shown as the hashed server seed on the History Details page; the server seed from the casino; the client seed from the player; the nonce, which rises by one per bet; and the selections, the numbers the player marked. The SHA256 hash of the server seed is shown before play; the client seed can be changed before any bet.

On verification the casino reveals the server seed, re-runs all five ingredients to regenerate the draw, and resets the nonce and the server seed. The player can hash the revealed seed and compare it with the round hash, then use Verify Results on the Keno tab of roobet.com/fair to replay the same logic. Because the selections are part of the input, a verification with a different set of marked numbers would produce a different draw; the exact selections of the round must be entered. More on the system in the chapter on fairness and licensing.

05Keno mistakes and fixes

The Keno-specific slips concern the number count, the selections at verification and the reading of the payout table.

06Keno in the catalogue

The catalogue row of 22 October 2026 lists Keno with the studio Roobet, the category provably fair, the tag roobet-games, Fun Play on and the release date 29 September 2025. Unlike most Originals it does not carry the arcade tag. Among the 15 Originals the game is first in the popularity sort and third in the weekly activity counter, behind the Blackjack Original and Dice. The sitemap of the operator lists it among the 15 Originals, and the Help Center article Welcome! names it as well.
