A return of 97
The figure sits in the game card in the casino catalogue. On that number Mini Mines lands in the upper third of this set: only Mines+ at 97.5 and both BGaming titles at 98.4 sit higher.
Mini Mines by OneTouch: one number out of six
Mini Mines is the most opaque card in this set. Of the six parameters mines games are normally compared on, the studio publishes exactly one: a stated RTP of 97. Board size, mine range, payout ceiling, stake range and release date appear neither on the OneTouch site, nor in the casino catalogue, nor in any review we could find.

What is known for certain
Three confirmed facts, and the list ends there.
Classified as a minigame
The catalogue files it not under instant win, as most of its neighbours are, but under minigames. The category implies a short round and a stripped-back interface, but there is no detail behind it.
Listed in December 2025
The date comes from the catalogue card and marks its arrival on the shop front rather than its release. OneTouch has published no actual release date anywhere.
Why we did not fill in the rest
The temptation was there, and it is understandable: the mechanics of the format are known and the gaps are easy to complete by analogy.
The mini in the title almost certainly means a reduced board - a 3x3 rather than a 5x5, say. Mine counts in mini versions are usually fixed, as in 1Tap Mines where there are always 3. And a small board cannot carry a high ceiling: across nine tiles the ladder runs into the board itself.
All of that is plausible and all of it is guesswork. In a text about money a plausible guess is visually indistinguishable from a verified number, and nobody will be able to separate them later - not the reader, and not us in a month. So there is an empty line here rather than a neatly derived value.
The only reliable route to the parameters is the game's own help screen inside a casino: studios are required to publish rules in-game even when they skip the shop front. The real payout ceiling will be there too.
Worth taking with this many gaps
The answer depends on what you actually select for in mines.
Return is the primary parameter and it is good here: 97 means the game keeps 3 percent of turnover. That beats Mines by Turbo Games at 95 and comfortably beats Mines Supreme 92% at eight percent.
But the format asks for two decisions, and both need data. How many mines to set cannot be answered without a range. How far to push cannot be answered without a ceiling. A game that names neither leaves you with only the first decision on the list, and even that one blind.
Practical verdict: at equal return it is simpler to take Hot-mines at the same 97, which states its board, its bomb range and its 20000 USD cap. Mini Mines is for anyone who specifically wants the short minigame format and is content to read parameters out of a help screen.
Frequently asked questions about Mini Mines
What board size does Mini Mines use
Unknown. Neither the studio site, nor the casino catalogue, nor any review names it. The mini in the title usually implies a board smaller than the standard 5x5, but no confirmation of that was found, and a guess is not a fact.
What is the RTP of Mini Mines
97. It is the only numeric value the studio publishes and it is confirmed by the game card in the catalogue. On return the game lands in the upper third of this set, level with Hot-mines and both Belatra Games titles.
What is the maximum win
Not published. The other fifteen games in this set state a cap either as a multiplier or in money; here there is neither. The only way to find out is to open the game help inside a casino.
Is a game with this little documentation worth playing
A return of 97 is a good figure and on that measure the game is no worse than its neighbours. But choosing in mines also requires a mine range and a ceiling, and neither exists here. At equal return it is simpler to take a game whose parameters are all stated.
