Bloons TD 6 review

Bloons TD 6 ranks first because it packs more tower defense into one game than anything else here. Ninja Kiwi lists 25 Monkey Towers, each with three upgrade paths and an activated ability, plus 17 Heroes with 20 signature upgrades and two special abilities apiece. There are more than 70 handcrafted maps, over 100 Monkey Knowledge meta-upgrades, Paragon upgrades, Boss Events, Odysseys and a Contested Territory mode where players compete for tiles on a shared map. Every map and mode supports four-player co-op, and single player works offline. The Content Browser lets players publish their own Challenges and Odysseys. At $13.99 on the US Steam store, 97% of 232,622 English Steam reviews are positive, the best record on this list. The trade-offs: Ninja Kiwi sells in-game items for real money, and the Steam version covers Windows and macOS only.
