Lunar Disc
IGT · Six-Ring Persistent Disc Meter
How the game works and what to check
Start with the documented Lunar Disc feature
Lunar Disc uses a six-ring meter above the reels. Collected Lunar Disc symbols fill the rings, and a completed meter spins for a feature or jackpot outcome.
Check that the game matches this guide. Read the help screen, note the bet and denomination, and check what stays on the screen after each spin. A different version may have different rules.

Read the number before the artwork
Lunar Disc uses a six-ring meter above the reels. Collected Lunar Disc symbols fill the rings, and a completed meter spins for a feature or jackpot outcome.
How many of the six disc rings are already filled.
Do not assume that being one ring away guarantees the very next spin completes the meter. The final collection event still has to occur.
Count the filled rings and verify bet level/machine setup before applying any play assumption.
How the disc meter works
Lunar Disc symbols add rings to the visible disc meter. IGT product material states that when all six rings are filled, the disc spins to reveal the award.
Why the state is easy to read
The machine presents a bounded six-step collector, so the visible ring count is a straightforward measure of accumulated progress.
The visible Lunar Disc signal only matters after bet, denomination, ownership and reset rules are confirmed on the installed game.
Machine checks
Filled ring count, final collection event, active bet and post-spin reset. Treat the exact machine help screen as the controlling rules reference and preserve both the starting state and the immediate post-award state whenever possible.
