20+ monkeys, 3 paths each
Every tower has three upgrade paths with wildly different top tiers. The combinatorics of a single map layout are effectively endless.

The premise
Bloons TD 6 is a tower defense game about monkeys popping waves of balloons, which is a bit like saying chess is a game about moving wood. Under the Saturday-cartoon art sits a dense strategic system: twenty-plus towers with three upgrade paths each, heroes with their own leveling arcs, and difficulty modes that strip away crutches until only genuine strategy survives.
It’s also the rare paid mobile game run as a live service done right: years of substantial free updates — new maps, towers, heroes, boss events — funded by an upfront price and genuinely optional cosmetic-and-convenience IAP.
Full honesty: this one does have in-app purchases. We include it anyway because the $6.99 game is complete without them — the shortcuts exist for people who want to skip a grind the game never forces on you.
Why you should play
Behind the cartoon monkeys is the most mechanically deep tower defense ever shipped. Seven dollars, seven hundred hours, zero requirement to spend again.

Casual rounds are a comfort blanket; the CHIMPS rule set removes every crutch and turns each map into a legitimate strategy exam.
