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

Variance · Systems & Chaos
Listening for randomised audio cues and executing a defensive checking routine.

Variance · Systems & Chaos
A match-three puzzle game themed around Disney's Frozen.
Five Nights at Freddy's 4 leans Variance (Systems & Chaos); Frozen Free Fall leans Variance (Systems & Chaos).
Five Nights at Freddy's 4 leans a little harder on execution, though the gap is small.
Five Nights at Freddy's 4
Reacting to breath audio cues within tight windows matters
Frozen Free Fall
simple swipe/tap matching inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Five Nights at Freddy's 4
Animatronic movement is RNG, not an adapting mind
Frozen Free Fall
no opponents, solo puzzle matching
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Five Nights at Freddy's 4
Random animatronic positions stay hidden behind audio cues
Frozen Free Fall
randomized piece drops each board
Five Nights at Freddy's 4 leans a little harder on optimization, though the gap is small.
Five Nights at Freddy's 4
Door-checking routines become a learnable optimal loop
Frozen Free Fall
pattern recognition and match planning
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.
