Mummy Mines: the only 4x4 grid in the set and autoplay with a brake
Every version of mines lives on three grid sizes: 3x3, 5x5 and the big squares at Turbo Games. Mummy Mines added a fourth - 4x4 - and it is the only place you can see it. Sixteen tiles give mathematics exactly halfway between nine and twenty-five, and above it sits the same jackpot reel as in Jackpot Mines by the same studio. RTP 97, demo below.
Why a grid in the middle is needed
The gap between nine and twenty-five tiles is bigger than it looks. A 3x3 grid is nine tiles, and a round on it ends in two or three clicks in any mode. A 5x5 grid is 25 tiles, and a round there can stretch to two dozen clicks. By feel the two modes have nothing in common, though the mechanic is one.
The sixteen tiles of a 4x4 grid close that gap. A round lasts longer than on the small grid but does not turn into a marathon; the multiplier ladder climbs noticeably but does not run into six figures as on 9x9 at Turbo Mines. If 3x3 feels too fast and 5x5 too long, the in-between option exists nowhere else - it can only be had here.
The winning symbol is a scarab, the losing one a mummy with a lit fuse. Belatra carried the character over from its own slot line, and in the lobby the game is recognised at once. A side effect: the mummy is funny, the explosion is cartoonish, and a loss looks amusing rather than annoying - the softer a lost round feels, the easier it is to start the next. Knowing the trick is more useful than avoiding games that use it.
Multipliers on the 5x5 grid at RTP 97
The studio does not publish the mine range, so all twenty-four rows are here, computed by the format's formula. On 3x3 and 4x4 the same formula applies with a different tile count. The jackpot reel is not in the table - it is played out separately.

At three mines the fifth tile is worth 1.96x, the tenth 4.90x - the same numbers as at Jackpot Mines and Hot Mines with the same return. The jackpot is not added on top; it is funded out of the same 97: ordinary rounds, all else equal, pay a touch more meanly than in a game without a pool, and in return there is an event that game does not have.

Autoplay as a limiter, not an accelerator
Before launch three things are set: how many rounds to play, how many tiles to open per round and how many mines to set. The round count is picked from preset values - 10, 20, 50 - or removed altogether, and that last option is the one to walk past.
The reason is not mathematics but how a session is built. The end of a batch of rounds is the natural point where the hand leaves the button by itself and there is a chance to assess what is going on. Unlimited autoplay removes that point, and the session ends not with a decision but with a balance.
Used properly, autoplay works here as a limiter. A batch of 10 rounds with a preset number of tiles to open is a pre-named exit point moved into the game settings. More on the technique in the strategy breakdown.
Mummy Mines against its neighbours on return
The three closest versions by RTP and the shared scenario on the 5x5 grid: three mines, five tiles.

| Jackpot Mines | 97 | 3% | x1.96 | 6-20 | jackpot up to 200 EUR |

From Jackpot Mines it differs in grid and settings, from Hot Mines in the reel and the picture, from Mini Mines in that here both grid and mechanic are known, while there only the return is. On the small 3x3 grid the large symbols read well, but on 5x5 the picture gets dense, and telling a scarab from a mummy in the corner of your eye is harder than a diamond from a bomb in minimalist artwork. For fast play that shows.
The 4x4 grid exists only here
Mummy Mines on the platform: three sizes, a jackpot reel and autoplay for 10, 20 or 50 rounds.
What people ask about Mummy Mines
What grid sizes does Mummy Mines have
Three: 3x3, 4x4 and 5x5. The middle size is unique in the set - no other game offers a 4x4 grid. Sixteen tiles give mathematics halfway between nine and twenty-five.
What hides under a tile
A scarab, a mine or a jackpot symbol. The first lifts the payout, the second ends the round, the third triggers a separate spin of a reel - and the reel decides whether it is an addition, the end of the round or the whole accumulated jackpot.
How does autoplay work
Three parameters are set: the number of rounds - 10, 20, 50 or unlimited - the number of tiles opened per round, and the mine count. Then the game runs by itself. The unlimited option is better left alone: it removes the only natural stopping point.
How does it differ from Jackpot Mines by the same studio
In grid and artwork. The jackpot reel, the stated RTP 97 and the overall round scheme are shared. Jackpot Mines has two grids, 3x3 and 5x5; here there are three thanks to the intermediate 4x4, and there is a fuller autoplay.
Does Mummy Mines have a demo
Yes, it opens right on this page from the Belatra showcase without an account: first a splash with a Play button, then the grid itself. All three sizes and autoplay work in the demo.
