head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Arcade racing with Mario Kart-style power-ups bolted onto licensed cars.

Execution · Pure Mechanics
Stacking wobbly bricks quickly while sabotage spells fly between players.
Blur leans Execution (Pure Mechanics); Tricky Towers leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Racing lines and dodging shots demand car control
Tricky Towers
Placing physics bricks fast under pressure is the core test
Blur leans a little harder on reads, though the gap is small.
Blur
Human racers bait and time power-ups against you
Tricky Towers
Timing spells against specific human rivals adds light prediction
Blur leans a little harder on variance, though the gap is small.
Blur
Power-up pickups and incoming attacks add chaos
Tricky Towers
Brick sequence and wobble physics inject chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Track knowledge and pickup routes are learnable
Tricky Towers
Stable stacking shapes are learnable patterns
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.
