GemCraftvsKingdom Rush
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.
GemCraft
Optimization · Pure Optimization
A tower defense game about engineering optimal gem combinations against scripted waves.
Kingdom Rush
Optimization · Pure Optimization
The genre-defining cartoon tower defense with crunchy upgrades and fixed waves begging for perfect solutions.
GemCraft leans Optimization (Pure Optimization); Kingdom Rush leans Optimization (Pure Optimization).

Axis by axis
Execution2 vs 2
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
GemCraft
Placing gems and towers has no twitch demand
Kingdom Rush
Light micro of hero and rally points
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
GemCraft
Monster waves are scripted, never adapting to player
Kingdom Rush
Wave compositions are fixed and previewable
Variance2 vs 1
GemCraft leans a little harder on variance, though the gap is small.
GemCraft
Wave composition is fixed once a level is known
Kingdom Rush
Almost fully deterministic waves
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
GemCraft
Combining gems for optimal tower output is the entire game
Kingdom Rush
Tower placement and upgrade routes are solvable
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
