Lost Mystery Chests











Lost Mystery Chests is a Betsoft video slot that’s also US-friendly. We always love reviewing such games.

Simply because online casinos can’t get slots from other software providers. Betsoft is a trusted studio with many great releases to its name.

At the same time, we feel some of them don’t match Betsoft’s lofty standards. Unfortunately, we have to break some news here.

It’s basically a copycat of Golden Tiger Ascent. The only difference is theme and game art changed from Asian to ancient Egyptian.

The slot has 3 reels, 3 rows, and a set of 10 paylines. The math model is capable of producing wins as high as 2,520x your bet.

Lost Mystery Chests is available at the best casinos online in the USA.

Betting Range

The betting range of Lost Mystery Chests starts at $0.10. If you want to win the jackpot you can bet as much as $150 at select casinos.



The theoretical RTP of the slot is 95.37%. That’s nothing to write home about and well below the par for the course.

Unfortunately, this might be the new Betsoft standard or close to it. If you don’t know what the average payback rate or RTP of a slots is. That site explains it well.



The graphics of Lost Mystery Chests are eye-catching and the slot machine’s best attribute.

If you like all things Egyptian, you’ll like what’s on the menu.

The low-paying symbols are hieroglyphs of sorts. Meanwhile, the high-paying symbols compliment the theme.

Therefore, showcasing anks, pyramids, and other paraphernalia.

For them, you can win up to 5x your bet, that’s if you find a winning combo of three symbols.

Treasure Chests Wilds are even better in that regard. They pay out 25x your bet for a combo and can sub other symbols as well.

Gameplay Features

Mystery Chests

Special Mystery Chest symbols can land on any spin. You can get up to 5 at any point. They stay closed until the spin stops.

Then, they produce a dramatic reveal and give you one of several possible rewards. These include high-paying symbols, instant cash prizes, Wilds and Scatters.

Free Spins

If you get 3, 4, or 5 Treasure Chest Scatters in view. They initiate the 6, 8, or 10 free spins, respectively.

You’ll also get a decent payout to go with that, up to 40x your bet. In any case, the real kicker is elsewhere.

The free spins feature guarantees you at least 3 Mystery Chests. You can find as many as 9 of them on any free spin, though, for a sweet payout potential!

Bonus Buy

Don’t want to wait for the juicy bits? Then use the Bonus Buy option and buy some free spins outright.

You’ll have to part with 40x, 53x, or 66x your bet. For that, you’ll get 6, 8, or 10 free spins, respectively.



We have to admit that we were a bit fooled when we first saw Lost Mystery Chests. We took it for a fresh Betsoft slot, but it’s basically a copy of a previous Betsoft release.

Especially since that original slot came only a month before this release. Is Betsoft taking shortcuts? Generally speaking no, but it sure did with this release.

Lost Mystery Chests is not the best 3×3 slot. It’s one of those slot machines that lacks innovation. We played the slot machine with free credits at an average bet of $15.

We used the buy feature a few times and with our 6 free spins won $1,250. On one occasion we received 9 treasure chests!

The more treasure chests the bigger the payout in the free spins.

The RTP is slightly below 96% and drags the slot down a bit. Gold Tiger Ascent is similar to this one.

Other than that, Lost Mystery Chests is a bland affair, we’ve played better!


Alternative Recommendation

For a fresher alternative, you should check out another Betsoft slot called Triple Juicy Drops.

It’s a 5×5 slot with wins for 3+ matching symbols on horizontal or vertical lines.

The graphics look neat the maximum payout is 20,534x. That’s alongside the high volatility and below-average 95.73% RTP.

You can look forward to Cascades, Wilds, Free Spins, and three Prize Wheels. The Prize Wheels are where the fun is.

Fill them and you’ll get to spin them, for interesting rewards a sweet 20,000x fixed jackpot awaits you.
