head to head
Marvel Snap asks more than Frozen Synapse, and the gap is variance.

Reads · Mind & Math
A simultaneous-turn tactics game where you plot moves against a human's unseen plan and watch both resolve.

Reads · Grand Arena
A fast card game where the snap mechanic makes reads central.
Frozen Synapse leans Reads (Mind & Math); Marvel Snap leans Reads (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Frozen Synapse
Simultaneous turns remove all dexterity
Marvel Snap
No execution component
Frozen Synapse leans a little harder on reads, though the gap is small.
Frozen Synapse
You must predict a human's hidden plan each turn
Marvel Snap
Snap/retreat decisions are pure opponent psychology
Marvel Snap leans clearly harder on variance.
Frozen Synapse
Hidden enemy orders and fog on some modes
Marvel Snap
Hidden locations and draws drive swings
Frozen Synapse leans a little harder on optimization, though the gap is small.
Frozen Synapse
Line-of-sight geometry and timing are calculable
Marvel Snap
Deck construction and curve still matter
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.
