head to head
Secret Neighbor asks more than Agar.io, and the gap is variance.

Reads · Competitive PvP
A browser arena where your cell eats smaller players and flees bigger ones.

Reads · Bluff & Deduction
Kids loot a house for basement keys while one of them is secretly the Neighbor in disguise.
Agar.io leans Reads (Competitive PvP); Secret Neighbor leans Reads (Bluff & Deduction).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Agar.io
Mouse steering and split timing
Secret Neighbor
Chases, juking, and grabs need real motor skill.
Secret Neighbor leans a little harder on reads, though the gap is small.
Agar.io
Baiting and predicting human blobs decides fights
Secret Neighbor
The disguised Neighbor wins by out-modeling suspicious kids.
Secret Neighbor leans clearly harder on variance.
Agar.io
Spawn locations and lobby makeup random
Secret Neighbor
Hidden Neighbor identity and random key spawns obscure information.
Secret Neighbor leans a little harder on optimization, though the gap is small.
Agar.io
Split-merge math is shallow but real
Secret Neighbor
House layouts and key routes are mappable with play.
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.
