Niva Casino is a deep-water tap arcade. Glass blooms rise from the vents
below Cinder Reef, and you are the last diver on the line: burst them before
they crown the surface and choke the light out of the water.
Tap one bubble and every touching bubble of the same species goes with it, so
reading the column beats hammering at it. Wait a beat, let a cluster gather,
then take the whole group in a single tap. Bursts made within two seconds of
each other build a chain multiplier up to ten deep, and every burst charges a
pressure gauge — fill it and your next tap leaves as a shockwave that clears a
wide ring of anything in its way.
WHAT'S IN IT
- Sixty dives across six reefs, from the shallow Shoal Gate to the Lantern
Crown, each raising rise speed, species count and pop quota.
- Four bubble species with distinct glass, colours and shapes, plus an optional
species-mark setting that prints pips on every bubble so colour is never the
only cue.
- A four-piece booster kit you buy per use: Scout lights the biggest cluster,
Stillwater holds the column for six seconds, Surge fills the pressure gauge,
and Riptide sweeps out whichever species is thickest.
- An outfitter stocking four gear tracks — lung capacity, pressure tuning, reef
glass and tidal grip — that permanently change how every later dive plays.
- Twelve accolades, an eight-entry reef codex that fills as you play, a daily
tribute, and a full diver's log of career records.
NO STRINGS
No ads. No in-app purchases. No accounts, no sign-up, no email. No network
requests at all — the whole game runs offline, and your log never leaves your
phone. One currency, earned by playing, spent on things that actually change
the game.
Three stars means clearing the quota with more than half your air still on the
clock. Sixty dives is the easy part; sixty clean ones is the run worth having.
