Monster Tree: Bubble Shooter is a fantasy bubble-popping game. Non-player characters Meiling and Arya are trying to build a treehouse for Arya. The player must pop clusters of bubbles to plant, water and grow a magical monster tree for this purpose. Additionally, their actions help them to collect energy from the tree, which gives them access to the bubble-popping side games and fruit that they collect to access, feed and rejuvenate helpful monsters.
The player receives a ring shooter, two swappable projectiles and a stretch-style dotted aiming arrow. They must pop clusters of three or more color-matching bubbles to collect water. Over time, the game provides them with boosters and upgrades to make creating clusters easier. They can use a booster that makes the arrow longer and adds a targeting bubble to it. They can also access a third swappable projectile.
Monster Tree: Bubble Shooter makes play difficult in several ways. The player can only collect water droplets as part of a cluster. With water vials and boosters, they must take an extra step. These bubbles enlarge and block rows of bubbles. The player must then perform a separate shot with a matching projectile for collection.
That said, the game rewards the player handsomely. They receive bonuses when they pop clusters in streaks. They also receive a lot of boosters by completing side tasks like reaching a specific score.
