Betsoft have been around for a good while, so in their collection, they have some very old-school slots, like Lost, for example. This game was released in 2012 and after a long and eventful decade, we are getting a sequel called Lost Mystery Chests. We don’t think that anyone, besides Betsoft themselves were expecting to receive a sequel to such an old slot, but we’re down for the idea. Years of innovation separate these games, so we wonder, how much better is the new Lost Mystery Chests slot.

There is a good chance, that you may not be familiar with the original Lost slot. The story is about a world-renowned archaeologist named Dr Dakota Bones, who travels across all of Egypt, searching and looting old tombs and pyramids. We know plenty such heroes, most notably Rich Wilde from Play’n GO, but even though Mr Bones is older, his deeds are lesser-known. Perhaps, things will change with Lost Mystery Chests.

Gameplay and Payouts

Betsoft have always been quite fond of 3D graphics, even though most of the time they look a bit wonky and odd. Years have been good to Mr Dakota Bones, as he hasn’t aged a bit, still smirking and plotting his next big discovery. Lost Mystery Chests slot has an authentic and slightly intimidating Egyptian style presentation. The slot consists of 3 reels and 3 rows, providing a very classic 3 by 3 layout. This game certainly has more animations and it feels much livelier than the original Lost slot.

As you can imagine, you can’t fit in too many paylines in a 3x3 layout, so on Lost Mystery Chests, we have 10 of them. Ancient tablets with hieroglyphs are 3 low symbols, while two high symbols are a pyramid and an ankh cross. Even though they’re generic, we really enjoy how these symbols look, they match well with the general theme and the style of reels.

Additionally to improved visuals, also payouts have received a much-welcomed change. From the dull 93.80% RTP, we’re jumping up to 95.37%. It’s a nice improvement, although, by some, anything below 96% is still considered on the low side. Lost Mystery Chests is a medium volatility slot with a decent max win of 2,520x. The bet range for this Betsoft slot is 0.10 – 150.

Bonus Features

The name of the game already suggests the main idea behind this slot. Lost Mystery Chests biggest selling point is these Mystery Chests. These are simple treasure chests that may contain Scatters, Wilds, High-paying symbols or instant cash prizes. On every spin, there is a chance that 3- 5 Mystery Chests may land.

If Mystery Chests reveal 3, 4 or 5 scatters, then 6, 8 or 10 Free Spins are awarded, plus a payout of 5x, 10x or 20x respectively. During Free Spins, each spin guarantees 3-9 Mystery Chests. Lost Mystery Chests Free Spins can also be purchased for 40x, 53x and 66x depending on how many Free Spins you choose.

Betsoft themselves are calling their original Lost slot iconic, which we think is a bit of an overstretch but for iGaming OG’s it very well might be so. After a whole decade, we’ve received a nice sequel that brings back the long-forgotten, dust-covered name of Dakota Bones. Lost Mystery Chests is far from the most epochal return, but it is generally a well-built slot, with good visuals and pleasant payouts.
