Why this machine isn't on our advantage play list
WMS / Light & Wonder hold-and-spin family. The Lock It Feature triggers when 3-5 heart symbols land on a row, locking them with credit or progressive values; additional adjacent hearts become sticky and increase locked values.
Night Life uses gold coin wilds during free spins for spin-by-spin multipliers.
Diamonds uses an alternate reel set with extra hearts plus tall nudging wilds.
Both share Mini / Minor / Major / Grand progressives but with no must-hit-by caps.
The Lock It Feature is volatile and dramatic, but it's all event-triggered.
Locked hearts and multipliers reset completely after each bonus.
No carry-over state between players, no must-hit-by caps on the progressives.
AP-style scouting (looking at the cabinet to estimate value before sitting down) doesn't apply here.

For vault-style banking with hold-and-win feel: Cleopatra's Vault
