Betting Options and Bonus Features
Keys To The Sea is an adventurous tumble slot built on a 6x5 layout inside an underwater temple. From the get-go, Popiplay gives you the option to play with regular odds or with a Boost Chance. This is an optional feature that can be toggled on and off. Should you wish to enable it, your bet size is increased by 25% but in return, you’ll get a higher chance of activating the game’s bonus round.
In the base game, your goal is to connect 8+ matching symbols vertically or horizontally. Doing so will remove the winning symbols from the grid, award you with a cash prize corresponding to the pay table, and also drop new symbols from above to replace your winning symbols. This tumbling sequence repeats indefinitely as long as there are winning combinations on the grid.
Overall, there are 5 low-paying symbols illustrated by shiny gems and also 4 premium symbols. Premium symbols have special icons of magical conches and jeweled crowns as well as other deep sea-themed images. Gems reward cash prizes between 0.25x and 10x your stake, whereas premium symbols deliver much more - between 1.5x and 50x.
There is also a special Scatter symbol, which is the fabled Key To The Sea. You’ll need at least 4 keys to trigger the Free Spins bonus game. Landing 4, 5, or 6 Scatter symbols will grant you 10, 20, or 30, free spins respectively. You’ll also get a decent cash prize of 3x, 5x, or 100x, depending on how many Scatters you land.
During the Free Spins bonus round Poseidon himself will take you deep into the underwater chamber where not only do you get free spins but also unlock a special multiplier symbol, illustrated by Poseidon’s trident. Whenever you manage to land this symbol it will take a random multiplier value of up to 100x! At the end of a tumbling sequence, all trident symbols are added together along with their multiplier and applied to your win, which can result in crazy big wins.
The Keys To The Sea are still available in the bonus game and landing more will retrigger your bonus round. If you, however, wish to enjoy the bonus game without much fuss you can also use Popiplay’s Bonus Buy option. For 100x your stake, Popiplay lets you skip the base game and unlock the bonus game right away.
Roshtein’s Take
Keys To The Sea could use a little bit more flavor in the base game. It's a plain tumble game with no extra sass. The bonus game though, is excellent! The transition to it is seamless as it's super simple. The new multiplier symbols are rewarding and feel extremely volatile.
