Uncover the mystery of a lost civilization and win massive rewards. At 555king, Lost City Slot offers incredible free spins, wild multipliers, and thrilling bonus rounds waiting to be triggered.
Lost City slots takes you on an expedition through a mysterious, forgotten city. Its theme sets it apart from ordinary slots — you're not just spinning reels, you're uncovering the hidden treasures of an ancient civilization.
The game is available on the 555king platform with impressive graphics and sound effects. It features 5 reels and 3 rows across 30 paylines. The excitement builds with every spin, as Free Spins or a bonus round can kick in at any moment.
This game has become hugely popular among Bangladeshi players thanks to its high RTP (96.5%) and how frequently its bonus features trigger. At 555king, betting options start from as low as ৳10, catering to players of all levels.
The visual design blends ancient Egyptian and Mesoamerican civilizations. Temple stones, ancient maps, mysterious idols, and hidden treasure are the game's key symbols. Special win animations bring the action to life with every payout.
Lost City Slots features 10 symbols in total, each with its own value and special properties. Knowing the symbols makes it much easier to understand which combinations pay out and how much. Review this list before playing on 555king.
| Symbol | Name | Type | 3 of a Kind | 4 of a Kind | 5 of a Kind |
|---|---|---|---|---|---|
| Lost City Crystal | Wild | Acts as a substitute symbol | — | 500x the bet | |
| Treasure Map | Scatter | 5x and Free Spins Trigger | 10x | 20x | |
| Lost Temple | Premium | 30x Bet | 150x Bet | 500x the bet | |
| Ancient Stone | Premium | 20x the bet | 100x the bet | 300x the bet | |
| Antique Compass | High Value | 15x Bet | 75x Bet | 200x Bet | |
| Ancient Urn | High Value | 10x the bet | 50x the bet | 150x Bet | |
| Mystery Key | Mid Value | 8x the bet | 40x Bet | 100x the bet | |
| Ace | Low Value | 5x Bet | 25x Bet | 75x Bet | |

The Wild symbol (Crystal) substitutes for any symbol except the Scatter, significantly boosting your chances of a win. The Scatter symbol (Map) triggers free spins when 3 or more land anywhere on the reels — no payline required. On 555king, keeping an eye on these two symbols is the foundation of any solid strategy.
The variety of bonus features is what makes Lost City Slots one of the most popular games on 555king. Each feature on its own can open the door to massive wins.
Landing 3 or more Scatter (map) symbols anywhere on the reels triggers the Free Spin Round. 3 Scatters = 10 free spins, 4 = 15, and 5 = 25 free spins. All wins during this round are multiplied by 2x. On 555king, landing more Scatters during the Free Spin Round adds extra free spins.
During the Free Spins round, if a Wild symbol (Crystal) lands on any reel, it fills that reel's entire column with Wilds — this is known as an Expanding Wild. Three rows filled with Wilds means simultaneous wins across multiple paylines. A special animation plays on 555king's screen when this happens.
In the main game, landing 3 or more special temple symbols together triggers the Treasure Hunt bonus game. In this mini-game, you open hidden treasure chests on a map. Each chest contains either a bet multiplier or free spins. Some chests reveal a "Treasure Found" message, which awards the highest prize.
One of Lost City Slots' standout features is its cascade mechanics. When you win, the winning symbols disappear and new ones drop down from above. If the new symbols form another win, the process repeats. Consecutive wins within a single spin mean a growing multiplier is added with each cascade.
Landing 5 Guardian symbols on the same payline wins the game's top prize — the City Guardian Jackpot. This can pay up to 5000x your bet. It's a rare event, but many players on 555king have already hit it. The Free Spin Round gives you the best shot at triggering this jackpot.
On each spin, mystery symbols appear randomly at certain positions on the reels. Once the reels stop, all mystery symbols simultaneously transform into one specific random symbol. If it turns out to be a high-value symbol and there are many of them, the result is a big win. At 555king, this feature keeps the game unpredictable and exciting.
To get the most out of Lost City slots, be patient and wait for the Free Spins round to trigger. The combination of Expanding Wilds and a 3x multiplier makes Free Spins a prime opportunity for big wins. At 555king, you can use the Auto Spin feature to run a set number of spins, and it will automatically stop when a bonus is triggered.
Lost City slots at 555king offers flexible betting options to suit players of every budget. Choosing the right bet size is key to a great gaming experience.
