Bloons TD 6 leans Optimization (Pure Optimization); Hexcells Infinite leans Optimization (Pure Optimization).
Bloons TD 6Hexcells Infinite
Axis by axis
Execution1 vs 1
Even - both lean on execution about the same.
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 0
Bloons TD 6 leans harder on variance: Wave order is deterministic; tiny targeting randomness
Optimization9 vs 10
Hexcells Infinite leans harder on optimization: Chaining constraint deductions across hex grids without ever guessing
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
