Keno, as Raging Bull presented it in 2015
This article was written in 2015 and we keep it as a record of how the online casinos of that time presented their games and promotions. The operators, offers and figures it mentions may no longer exist or may have changed, and nothing on this page is a current offer. 18+.
This article was first published in 2015, when Raging Bull, a casino with RealTime Gaming software (RTG, also the software of the Deckmedia casinos) that is not among the operators we work with, presented keno as a "specialty game" to lovers of the lottery and bingo, and we keep it as testimony of the game, not of the casino. The invitation to "open an account today" is the only part left out.
What the casino said about the game
On the keno card, the article explained, there were eighty numbers, of which the player chose up to fifteen (the maximum of most versions), after which the game drew its own numbers at random: the ones the player had picked lit up in yellow, and the ones he had missed were crossed out with an X. Fifteen, the text said, were drawn.
That figure we cannot check, since the classic keno (the one of the Nevada lounges, and of most online versions) draws twenty numbers out of eighty, so that a single pick is drawn one time in four, and the fifteen of the article may have been an imprecision of the time. The odds of matching all the picks fall quickly as the picks grow, which is what the paytable pays for.

How the game was played
The instructions took four lines, and they are kept here as they were. The player hovered over the numbers and clicked the ones he wanted, or pressed "Quick Pick" if he wanted them chosen for him, and pressed "Clear" to wipe the card (or clicked a number again to drop it), before choosing "Play 1", "Play 5" or "Play 10" to run one, five or ten games in succession with the same numbers.
The last button deserved a line the article did not write, since a player who marks ten numbers and presses "Play 10" at one dollar a game has spent ten dollars (ten times one) before the first result is read, and the same ten dollars at "Play 1" would have lasted ten decisions instead of one! A button's convenience is the casino's first, a rule worth remembering before you press anything.
The payouts it quoted
The release ended with a table of "features", turned into a sentence here: a "Major Moolah" payout of $20,000 (a figure that the page did not explain), a maximum payout of $50,000, the choice of one, five or ten consecutive games (the three buttons already described), a screenshot button, a help tab and the Quick Pick. A help tab counted as a feature, which tells how low the bar was.
What the table did not say is what keno keeps from the player. The house edge is, in most versions, well above the 2.70 per cent of a single-zero roulette, and it changes with the number of spots marked and with the paytable of each version, which is why the help tab (the one feature that mattered) was the page to read before you marked the first card.
The comparison with the lottery, offered as a compliment, was the most honest line of the release: in both games the player pays for a draw whose return is fixed by whoever prints the paytable, and a player who marks fifteen numbers buys a long shot, with the small consolations of the partial hits. The difference is the clock, since a keno draw takes seconds and a lottery takes a week.
Seen from 2026
Raging Bull is not among the operators of this site today, and the page does not link to it; the images lead instead to SlotoCash, a casino of the Deckmedia group with a Curaçao licence (an offshore licence, hence the conservative rating of our review), whose lobby, when we tried it in demo, still listed a keno among its "specialty games". The link is an affiliate link, as the box above says.
The game itself has not changed, since a keno is a lottery with a faster clock, and no button of 2015 or 2026 moves the share that the house keeps; what has changed is the page, which carries a licence, a rating and a method instead of a table of "features". The games we have played in demo are gathered in the slot hub, where this article is listed as testimony.
A player who prefers the slot to the card finds the current "free spins" offers, with the wagering counted, on our free spins page, and the no deposit bonuses of today on the world list, where you will find the terms read before the adjectives. The other announcements of those years (2014 and 2015) are kept in our news archive, in the tone in which the casinos spoke to their players.
