Rainbet roulette outside bets are the simplest way to approach the wheel: choose red or black, or odd or even, and aim for a 1:1 return. That simplicity does not remove the house edge, so the key is understanding which outcomes are included and which are not. This guide explains the rules, compares the choices, and places them in the wider context of rainbet casino play for New Zealand readers.
How Rainbet roulette outside bets work
Outside bets cover broad groups of numbers rather than individual pockets. Red and black divide most numbered pockets by colour, while odd and even divide them by number type. A winning outside bet normally pays even money: a $10 stake returns $20, including the original stake. The zero pockets sit outside these groups, which is where the house gains its mathematical advantage.
Red and black compared with odd and even
Red and black are colour choices, while odd and even are number classifications. On a standard single-zero wheel, each has 18 qualifying numbers out of 37. The same is true on a double-zero wheel, but the extra 00 increases the disadvantage for the player. The colour or number pattern does not make one option more likely than another on the next spin.
- Red covers 18 red pockets.
- Black covers 18 black pockets.
- Odd covers 18 numbered odd pockets.
- Even covers 18 numbered even pockets.
- Zero is not red, black, odd or even.
Rainbet roulette odds and payouts
The practical difference between outside bets is not the advertised payout but the wheel used. On a single-zero wheel, a 1:1 bet wins 18 times out of 37 in the long run, while the zero loses. That produces a house edge of about 2.7%. A double-zero wheel has 38 pockets, giving the house edge of about 5.3% on the same bet.
| Outside bet | Qualifying pockets on single-zero wheel | Typical payout | What loses |
|---|---|---|---|
| Red | 18 | 1:1 | Black and zero |
| Black | 18 | 1:1 | Red and zero |
| Odd | 18 | 1:1 | Even and zero |
| Even | 18 | 1:1 | Odd and zero |
| Zero | 1 | 35:1 | All other pockets |
Past results do not change these probabilities. A run of five reds does not make black “due”, and a recent zero does not make another zero less likely. That matters when comparing systems such as doubling after a loss: the stake may change, but the wheel’s probabilities do not.
Rainbet table games and roulette formats
The Rainbet catalogue claims more than 8,000 games across casino and sportsbook categories, although independent reviews report different totals. Its named providers include Evolution, Pragmatic Play, Relax Gaming, BGaming, Hacksaw Gaming and Nolimit City. Roulette availability can vary by provider, lobby and location, so check the individual game page before relying on a particular wheel.
Choosing a wheel before placing an outside bet
The first useful check is the number of zero pockets. A single-zero European-style wheel is mathematically preferable to a double-zero American-style wheel for red, black, odd and even. Also inspect the displayed rules, minimum stake, maximum stake and whether the game is live or automated. Rainbet advertises live casino content supplied by Evolution and also offers in-house Originals, including EOS Roulette.
Game descriptions may show return-to-player information, but roulette RTP depends on the wheel and rules. For Originals, Rainbet says provably fair results can be checked using a client seed, hashed server seed, nonce and bet ID. That process helps verify the result after the spin; it does not remove the house edge.
Using bonuses on outside bets
Rainbet’s official help information describes a first-deposit promotion with a 100% match and 40x wagering on the deposit plus bonus. For example, $100 deposited with a $100 bonus creates $200 in play funds and a stated turnover requirement of $8,000. The published terms also say games above 97.4% RTP are disabled while the offer is active.
Why bonus terms matter at the roulette table
Roulette can be restricted or contribute differently under casino promotions, so read the live terms rather than assuming every outside bet qualifies. The official material gives a maximum-bet rule of 1% of the deposit, while some reviews report 2%; that conflict should be resolved with support before playing. A bonus can also block withdrawals in the bonus currency until its conditions are met.
- Open the promotion terms before depositing.
- Check whether the selected roulette game contributes to wagering.
- Confirm the maximum permitted stake for bonus play.
- Track turnover separately from cash balance.
- Withdraw only after the account shows the relevant conditions are complete.
Deposits, withdrawals and account checks
Rainbet is crypto-first, so a New Zealand player should not assume the account balance or settlement currency is NZD. The stated minimum deposit is $15 or equivalent, while the minimum withdrawal is $15. Rainbet says it charges no own withdrawal fee, although blockchain network fees can still apply. Published estimates give 5 to 15 minutes for operator processing, followed by 5 to 45 minutes on the blockchain.
What to check before funding a roulette session
Supported crypto assets include options such as BTC, ETH, USDT, USDC, LTC, SOL, TRX, DOGE and XRP, but the available network must match the wallet address. An on-site crypto purchase service is reported to accept cards and digital wallets through payment partners; that is different from a confirmed direct NZD casino deposit method. Identity checks may request photo ID, a selfie, proof of address and source-of-funds information.
Responsible play and account controls
Roulette outside bets feel controlled because the choices are easy to understand, but repeated 1:1 bets can still produce fast losses. Rainbet’s help material says it does not provide deposit limits. It does offer rolling daily, weekly and monthly net-loss limits, along with cooling-off, self-exclusion and permanent exclusion tools. Optional two-factor authentication also covers login, withdrawals, tips and vault transfers.
Set a spending limit with your bank or wallet before opening the casino, and treat every stake as money that may be lost. If gambling is causing stress or financial difficulty, contact the Gambling Helpline on 0800 654 655. Gambling is for people aged 18 and over.
Rainbet and New Zealand’s changing rules
Rainbet’s operator is listed as RBGAMING N.V., registered in Anjouan, Union of the Comoros. The dossier records an Anjouan licence running from 14 June 2024 to 13 June 2027, but it found no evidence of a New Zealand licence or DIA approval. That distinction is central: an offshore licence is not a New Zealand licence.
New Zealand’s Online Casino Gambling Act 2026 received Royal Assent on 27 April 2026 and came into force on 1 May 2026. The new regime is being introduced in stages, with the Department of Internal Affairs responsible for licensing. The published transition information indicates that offshore operators serving New Zealand customers face a deadline of 1 December 2026. Check current DIA guidance before opening or funding an account.

Is a Rainbet outside bet a sensible choice?
Red, black, odd and even are comparable bets: each pays 1:1 and covers 18 numbers on a single-zero wheel. The better choice is therefore usually the table with the better wheel rules, not a particular colour or number pattern. A single-zero game, clear terms and a stake that fits your budget matter more than a betting system.
| Decision point | More favourable sign | Reason |
|---|---|---|
| Wheel layout | Single zero | Lower house edge than double zero |
| Bet payout | 1:1 outside payout | Easy to calculate and compare |
| Bonus wagering | Clear contribution rules | Reduces the risk of unexpected restrictions |
| Withdrawal | Verified wallet and network | Helps prevent transfer errors |
| Account protection | Loss limits and 2FA enabled | Supports spending and security control |
Conclusion
Rainbet roulette outside bets are straightforward, but straightforward does not mean low risk. Red, black, odd and even have the same basic coverage and payout, while the zero pockets create the house edge. Compare the wheel, read bonus restrictions, verify payment details and confirm the current New Zealand legal position. If the numbers do not fit your budget, skip the spin rather than chasing a result.
Frequently Asked Questions
These answers cover practical points that can affect a New Zealand player’s roulette decision.
Does red have better odds than black on Rainbet?
No. On a standard single-zero wheel, red and black each cover 18 of 37 pockets. The same applies to odd and even. Previous spins do not alter the next result, so neither colour has a built-in advantage over the other.
Can zero be covered by an outside bet?
No. Zero is separate from red, black, odd and even. A zero result normally loses all four outside bets. Some roulette games may offer special zero rules, so check the paytable before staking.
Are Rainbet roulette winnings settled in NZD?
NZD settlement is not confirmed. Rainbet uses crypto-based wallets, and published information does not establish NZD as a display or settlement currency. Check the wallet and conversion details before depositing, including any exchange-rate or network costs.
Is Rainbet licensed in New Zealand?
No New Zealand licence was identified in the available information. Rainbet is associated with an Anjouan licence, which is separate from DIA licensing. New Zealand’s online casino framework is changing, so check current government guidance before using an offshore operator.
