Balloon Tower Defense 4 ((better)) -

Even years later, the balance of BTD4—where every tower felt viable and every map felt like a unique puzzle—keeps it playable and beloved by the community. It wasn't just a game about popping balloons; it was a masterclass in strategic design.

We conducted 100 simulated runs of BTD4 (Standard mode, Medium difficulty, Monkey Lane map) using a custom Python script that replicated tower behaviors. Independent variables: tower mix (primary: Dart, Tack, Cannon; secondary: Ice, Glue, Super Monkey; tertiary: Banana Farm, Monkey Village). Dependent variables: rounds survived, total cash spent, and "leak rate" (bloons reaching the exit). Qualitative strategies were crowdsourced from the Speedrun.com BTD4 leaderboard community (n=12 expert players). balloon tower defense 4
