Bet Type Rules at a Glance
Anyone opening an account with us as a Rhino online casino player agrees to the rules governing each bet type before staking. These rules apply to every market on the line and determine how a slip is settled.
| Bet type | Selections | Payout formula |
|---|---|---|
| Single | 1 event or market | Stake x odds |
| Express (accumulator) | Minimum 2, maximum 30 | Stake x product of all odds |
| System | Up to 16 events | Total stake split equally across combinations |
A 10 unit single at odds of 2.5 returns 25 units, while an 8 unit express across three selections at 2, 3.5 and 2.5 returns 140 units. These formulas are fixed and cannot be altered once a slip is confirmed.
Account Conduct and Selection Rules
Every account holder must follow the selection rules written into these terms. On express bets, all selections must win and all selections must be independent of one another; dependent outcomes, such as a match result combined with the correct score of the same match, cannot be placed together and the slip is rejected with an error. Several independent markets from the same event, such as a main market alongside a statistics market, can still be combined on one slip.
System Bet Conduct
A system bet combines several accumulators of equal size, with the stake split equally across every combination. In a 2/3 system staking 12 units across three selections at 2, 3.5 and 2.5, four units go into each of the three combinations; if one selection loses, only the combination excluding it is paid out, but if two or more selections lose, the whole system bet loses. We reserve the right not to offer accumulators on certain events, which is shown on the betting line at the time.
Bonus and Insurance Clauses
Where a promotional clause applies, such as accumulator insurance, it is announced in advance on the site or within the betting system before it takes effect. The stated condition for this clause is that an accumulator contains six or more selections and only one of them loses, in which case the stake can be refunded; each selection must also meet a minimum odds requirement as published with the offer. Full terms for any current offer are set out on our welcome bonus page.
We expect every account holder to review these clauses before relying on them, since insurance offers are applied at our discretion and are not automatic on every qualifying slip. Any dispute over how a clause was applied can be raised through our complaints process, which explains what happens after a case is submitted.
Terms and Conditions Questions
-
How many selections can I combine on an accumulator at Rhino?
An express bet needs a minimum of 2 selections and can hold a maximum of 30. Every selection must be independent, and dependent outcomes from the same match are automatically rejected by the slip.
-
If a selection within a system bet loses, what happens next?
In a system bet, only the combinations that exclude the losing selection are paid out. If two or more selections lose in a 2/3 system, the entire system bet loses, so only part of the stake is at risk per combination.
-
Can I combine the match result and correct score of the same game?
No. These are treated as dependent outcomes under our terms, and the slip shows an error if you try to combine them. Only independent markets from the same event can be combined.
-
How does accumulator insurance work?
Where offered, if an accumulator has 6 or more selections and only one loses, the stake can be refunded, subject to a minimum odds condition per selection. This offer is applied at our discretion and announced in advance.
-
How many events can a system bet include at most?
A system bet at Rhino can include up to 16 events, combined into several accumulators of equal size with the total stake split evenly across all combinations.
-
Where can I complain about how a bet was settled?
Any dispute about selection rules, payout formulas or a rejected slip can be raised through our complaints channel, where we explain the next steps for reviewing the case.
