Bloons TD 6 - The game features a variety of cute monkeys as the main characters of the Square Tower game. Each monkey has different skills and the player needs to deploy them wisely on the routes that the balloons pass through to stop those balloons from passing in front of them. There are 60 maps in the game, divided into four categories: Beginner, Intermediate, Advanced and Expert, while each map is also divided into three main types: Easy, Medium and Hard.

The core gameplay: players need to make full use of the various monkey towers, upgrades, heroes and activation skills to build the perfect line of defence and smash every balloon that appears. If a balloon passes through the defensive line set up by the player, it will deal damage to the player's blood level, and once the player's blood level is zero, the game will end in failure. Conversely, when all balloons generated in the current turn are broken, the challenge is successful to start the next turn. Be aware; if one of the fronts is disintegrated by a balloon, the player's combat power is reduced and will be countered by the balloons, making it vital to deploy your formation appropriately to ensure your final victory. In each round of the level, players are given 1 gold coin for each balloon they break, and can use the coins gained to build different types of defence towers, or upgrade the ones they already have to deal more damage to the balloon soldiers.

All in all, the fact that the game has received a 96% positive rating from nearly 70,000 players since its release in 2018 for its other cute little monkey shapes, with an intuitive yet varied balloon setting, speaks volumes about how good it is. It can be considered a sincere game that has to be played.
