Vega Mix: Sea Adventures is a match-3 game that features an underwater treasures theme. Vika and Raccoon are back! While on vacation, they decide to look for hidden wonders. In a submersible at 5,000 fathoms below, they need the player's help to clear their path, light their way and make discoveries. The player completes these tasks by winning match-3 games with a limited number of moves and collecting stars.
The player performs classic match-3 moves. They swap two items near matching items on checkerboards to create rows and columns of three or more matching marine-themed items. They also complete separate tasks, such as collect a specific number of these items, break crates and ropes, and open and clear away large and small suitcases.
Vega Mix: Sea Adventures provides the player with special items and boosters. For example, the player creates special items by forming longer and unique match lines. With their actions, they can create bombs, pinwheels, rockets and spinners. To activate an item, they merely need to select it. They can also swap it with a nearby item to change its location on a board. After so many levels, a booster unlocks on the right side of the screen. For example, they can unlock and use a shovel that removes an item without a move.
The game rewards the player with coins, stars, and eventually gifts. They use coins to buy boosters when they run out. They use the stars to complete special tasks assigned by Vika and Raccoon. The game allows them to earn more with ad views.
