Welcome to the Tomb - A treasure hunt awaits!
So, the theme of Lost: Mystery Chests is, as you might guess, an ancient Egyptian adventure. Think pyramids, hidden chambers and treasure chests filled with who knows what. The Betsoft slot game really leans into that whole 'Indiana Jones meets The Mummy' vibe, with relics, golden artefacts and hieroglyphics scattered across the reels.
Visually, it's pretty solid. The background is a classic Egyptian tomb, dimly lit with flickering torches, and the soundtrack adds a bit of mystery with typical 'ancient civilisation' style music. If you've played other Egyptian themed slots, this one will feel familiar, but there's a little twist - Mystery Chests. These bad boys are the highlight of the game and can randomly drop some serious rewards, which keeps things exciting.
What really makes this slot stand out is the way the Mystery Chests work. They can contain anything - instant prizes, Wilds, bonus rounds - so every spin keeps you on the edge of your seat. You never quite know what's going to happen, which is a nice touch for players who like a bit of unpredictability.
How to play - Spin your way to hidden riches
Like most modern slots, Lost: Mystery Chests is fairly easy to play. Even if you're a beginner, you'll get the hang of it in no time.
- The game is a 3-reel, 3-row slot machine.
- There are 10 paylines, so you have a decent number of chances to win.
- Betting is flexible - you can usually adjust your bet per line to suit your bankroll.
- Wins are paid from left to right, except for scatter wins, which can land anywhere.
Spinning the reels is as easy as hitting the 'Spin' button, but there's also an Autoplay feature if you want to sit back and let the game do the work for you. There's also a Max Bet button for those who want to go all in.
The main objective? Get the best symbols, trigger the bonus features and hope the Mystery Chests work in your favour.

Paytable - What's in the Chest?
As with any slot machine, some symbols are worth more than others. Here's a quick rundown of what you're looking for:
High paying symbols
- Wild - This is your highest paying symbol. Getting three of them can give you the best payouts in the base game.
- Ankh - Another high value symbol that fits the Egyptian theme.
- Golden Pyramid - Medium payout, but still worth keeping an eye on.
Low paying symbols
Egyptian Hieroglyphs - These don't pay much, but they appear often enough to keep your balance from dropping too fast.Special symbols
- Wild Symbol - This substitutes for all normal symbols, making it easier to complete winning combos.
- Scatter Symbol - These are the game changers. Get enough of them and you trigger special features (more on this below).

Special Features - Unlock the Mystery Chests!
Now let's talk about what makes Lost: Mystery Chests so exciting - the special features. When you play a slot, you don't just spin the reels and hope for a few small wins here and there. You want big rewards, free spins and bonus features that shake things up. This game delivers on that front with its Mystery Chests and Free Spins, all of which can seriously boost your winnings. Let's break them down one by one.
Mystery Chests - The Star of the Show
The Mystery Chest feature is the biggest reason to play this slot. Unlike regular scatter symbols in other games, these chests are more than just a key to free spins - they hold random surprises inside. Each time one lands on the reels, it opens to reveal a reward. You never know what you're going to get, adding an element of surprise to every spin.
Here's what you might find inside
- Instant Cash Prizes - Sometimes the Mystery Chest will just drop a nice chunk of change into your balance. This happens instantly and the amount depends on your bet size.
- Wilds - Some chests contain Wilds that can increase your winnings on that spin. As all Mystery Chests reveal the same symbol, getting multiple Wilds on the slot's small 3x3 grid is a really big deal.
- Scatters - Landing multiple Mystery Chests at once (usually three or more) can trigger the Free Spins feature, which is where the biggest wins often come from.
The best part? The game doesn't just hand out Mystery Chests randomly - they tend to appear more often during winning streaks, making the gameplay dynamic and rewarding.
Free Spins Bonus Round - Where the big wins happen
Get at least three Mystery Chest Scatters on the reels at the same time and you'll trigger the Free Spins round, where things really start to heat up. You'll get a different number of Free Spins depending on how many chests you land:
- 3 Scatters = 6 Free Spins + instant payout of 5x bet amount
- 4 Scatters = 8 Free Spins + instant 10x bet amount payout
- 5 Scatters = 10 Free Spins + instant 20x payout
During the bonus round, the game gives you far more chances to win than in the base game. Here's why:
- More Mystery Chests appear - As Mystery Chests are the main feature, they appear more often during Free Spins (3-9 on each spin). This means more cash prizes, higher winnings and a better chance of re-triggering the bonus round for even more Free Spins.
- Higher Payouts with Wilds, Ankhs and Pyramids - 3 or more Wilds or any of the high paying symbols means more profitable winning combinations more often.
- Winning Streaks - As the feature can be retriggered by landing more Mystery Chests, you can extend your Free Spins session well beyond the initial 6-10 spins, leading to some seriously big payouts.
Why these features make the game exciting
Unlike some online slots where bonus features feel tacked on, in Lost: Mystery Chests, these features are at the heart of the game.
- The Mystery Chests keep you on the edge of your seat because you never know what they're going to reveal.
- The Free Spins round is where the biggest payouts tend to be, and it doesn't feel impossible to trigger (which is a big plus).
Combined, these elements make Lost: Mystery Chests an energetic slot that doesn't get boring very quickly. If you're the type of player who enjoys random surprises, big multipliers and the chance to keep stacking wins, then this game delivers in spades.
Tips & Strategies - How to play smart
All right, let's talk strategy. Online slots are ultimately a game of luck, but there are a few things you can do to maximise your chances of walking away with a win.
- Manage your bankroll - Don't burn through your bankroll too quickly. As Lost: Mystery Chests is a medium volatility slot, you may go through a losing streak before hitting a big win. Start with smaller bets and gradually increase them as you start to get good payouts.
- Watch out for the Mystery Chests - Since the game revolves around them, it's a good idea to pay attention to how often they drop. If you go many spins without seeing one, you may be in a bad cycle and should consider lowering your bets until things turn around.
- Use the free spins to your advantage - The Free Spins round is where you can get the biggest payouts, so your goal should be to trigger it as often as possible. Keep an eye out for the Mystery Chests - they are your ticket to the bonus game.
- Don't chase losses - It's easy to get caught up in the excitement, but if you've had a rough session, it's okay to walk away and come back later. The game will still be there.
