The Rainbet casino, for players in Ireland

Eight thousand games is a number that means little until you take it apart. This page does: what the catalogue holds, who makes it, how the maths underneath works, and which parts deserve your attention if you are playing from the Republic.

Two facts first. The balance is in US dollars, so every figure here needs converting into euro in your head. And Rainbet’s casino holds no Irish licence — but neither does any other online casino, for a reason worth understanding before you open the lobby.

Why no online casino is licensed in Ireland yet

Ireland’s new regulator, the GRAI, licenses betting already. Casino is a step behind.

The Gambling Regulation Act 2024 contains a full gaming-licence regime: section 67(2) will make it an offence to provide a game without a gaming licence, and section 86 creates the licence. Neither has been commenced; the Irish Statute Book’s commencement table, updated to 6 October 2026, marks both as not yet in force. The GRAI says gaming licence applications will open during 2027 and 2028.

Until then the old Gaming and Lotteries Act 1956 still governs gaming, and it has no online licence at all. So an Irish player looking for a “GRAI-licensed online casino” will not find one, because the category does not exist yet. Rainbet’s casino runs on its Anjouan licence. When Irish gaming licences arrive, it will either apply for one or sit outside the regime, and the protections that come with it.

The full legal picture, including the betting side, is on is Rainbet legal in Ireland.

What is in the catalogue

Slots are the bulk of it, and they come in more shapes than the word suggests.

Classic slots stick to three reels and a few paylines — low volatility, frequent small returns, simple maths. Video slots are the modern default: five reels, bonus rounds, free-spin triggers and expanding features; Sweet Bonanza, Gates of Olympus and Sugar Rush are typical of the type. Megaways titles redraw the reels every spin into thousands of possible combinations, which is volatility by design. Jackpot slots feed part of each stake into a growing prize, which is why their base-game return is usually lower than a comparable fixed-prize game.

Live dealer tables stream from studios with a real dealer and real equipment: blackjack, roulette, baccarat, poker-based table games, and game shows such as Crazy Time, Lightning Roulette and Monopoly Big Baller. You see the wheel spin and the cards fall. The maths is the same as the digital versions.

Digital table games run the same blackjack, roulette and baccarat without a stream. They are quicker and usually take lower stakes, which cuts both ways: a smaller stake at four times the hands per hour is not a smaller exposure.

Rainbet Originals are the in-house set — Plinko, Mines, Dice, Crash, Limbo, Chicken Cross and others, plus its own blackjack — and they have a page of their own: Originals.

The studios behind the lobby

An operator does not build 8,000 games; it licenses them, and the studio names tell you more about quality than the operator’s marketing does.

Evolution supplies most of the live floor and the big game shows. Pragmatic Play works on both sides, with a huge slot catalogue and its own live studio. Hacksaw Gaming, NoLimit City, Play’n GO, Relax Gaming, Red Tiger, NetEnt, Yggdrasil, Quickspin, Thunderkick, BGaming, PG Soft, Habanero, Belatra and Spribe fill out the rest, each with a recognisable style: NoLimit City for savage volatility, Play’n GO and NetEnt for polished mainstream titles, Hacksaw for short, sharp, high-variance games.

This matters for a concrete reason. These studios supply operators licensed in regulated European markets, and to keep those relationships they put their games through independent test labs for RNG certification. That certification belongs to the game, not the website: a Play’n GO slot runs the same certified engine on an offshore lobby as on a licensed one — although, as explained below, the RTP setting an operator picks can differ.

What certification cannot vouch for is the operator: whether withdrawals are processed, whether bonus terms are applied as written, whether an account survives a dispute. Those depend on the licence, and Rainbet’s is from Anjouan.

Blackjack and roulette: the tables worth knowing

“Rainbet blackjack” is one of the searches Irish players make, so the tables deserve more than a line.

Blackjack has the lowest house edge in the casino if you play correct basic strategy, and a considerably higher one if you do not. Rules matter too: how many decks, whether the dealer stands on soft 17, what a blackjack pays. A table paying 6:5 instead of 3:2 for a blackjack costs you far more than any other rule change. Check the rules panel before you sit down, live or digital.

Roulette comes in European form (one zero) and American (two zeros), and the difference is not cosmetic: the extra zero nearly doubles the house edge. Choose single-zero tables. Game-show variants such as Lightning Roulette add random multipliers, paid for by lower standard payouts on straight numbers.

Baccarat is the simplest of the three — bet on banker, player or tie — and the tie bet, with its tempting payout, is the one with the worst edge.

RTP and volatility: the two numbers that matter

Return to player is the share of all money staked that a game pays back over a very large number of rounds. At 96% RTP the house keeps four cents per dollar in the long run. It is the price of playing, and the number to compare when choosing between games.

Two cautions. RTP describes millions of spins, not tonight. And many slots ship in several RTP versions — the same title can run at 96.5% on one site and 94% on another, depending on what the operator selected. The game’s own information panel shows the version you are playing. Check it there, not in a review.

Volatility describes how the return arrives. Low volatility means frequent small wins and a slow drain. High volatility means long dry spells and occasional big hits. Two slots with identical RTP can feel nothing alike, and volatility, not RTP, decides how long a bankroll lasts.

Choosing slots, rather than “the best slots”

There is no list of best slots that is true for everyone, and anyone selling one is selling something else. A better method:

1. Pick the volatility that fits your bankroll. Small balance, lower volatility. A volatile game needs a bigger bankroll and smaller stakes to survive its quiet stretches.
2. Check the RTP version in the information panel and prefer the higher one when a title offers a choice across sites.
3. Filter by studio, not genre. Studio style predicts whether you will enjoy a game far better than a category label does.
4. Learn the bonus round in demo mode before you pay for it.

Demo mode, and its trap

Most third-party slots and all the Originals offer a free demo with virtual credit. It is genuinely useful for learning what a feature does or how a Megaways engine behaves.

The trap is drawing conclusions. A demo session is short, and short sessions on a volatile slot produce wildly unrepresentative results either way. Use demo mode to learn mechanics, never to decide whether a game “pays”.

Bankroll, in one section

Choosing a stake matters more than choosing a game.

Decide the total you are prepared to lose before you open the lobby, and set your stake at a small fraction of it. On a $200 budget, spins of about $1 give you around two hundred spins — enough for variance to play out. At $10 a spin the same budget is twenty spins, which is not a session but a coin toss with animations.

The harder half: never raise the stake to win back a loss. It combines a bigger exposure with worse judgement at exactly the moment both are most dangerous.

The Irish angle

Two differences separate playing here from playing at an operator holding a GRAI licence for its betting today, and a gaming licence in future.

Tools. A licensee must offer you the facility to set a monetary limit (section 164 of the 2024 Act) and may not take payment by credit card (section 165). Rainbet offers its own loss limit, cool-off and self-exclusion, on its own terms, and nothing stops you funding through a card provider in its cashier.

Recourse. A licensee answers to the GRAI. Rainbet answers to its own complaints desk and, beyond that, to Anjouan.

Neither point says the games are unfair — the certifications exist for that. It says everything around the games is unsupervised from Ireland, which is a different kind of risk from the one most players watch for.

The bonuses page covers the welcome offer and its wagering, the VIP page explains rakeback, and the crypto page covers funding, since there is no euro route in.
