When lit — is a slot machine instruction indicating that a payout, multiplier, or feature only applies while a specific lamp or on-screen indicator is illuminated. You’ll see it on classic reel glass and modern video slots, usually near a symbol, payline, or bonus label. When the light is on, the condition is active.
Understanding When lit
In casino gambling, When lit meaning refers to conditional rules tied to an indicator lamp or UI highlight. The When lit definition is that the stated benefit—extra pays, jackpots, unlocked paylines, or features—applies only while the light is illuminated. This matters because it clarifies eligibility, prevents payout disputes, and guides bet sizing: some lights trigger only at certain stakes or after a prerequisite event. Understanding these signals helps a player read machine state, pace bankroll, and avoid costly assumptions.

FAQs
What does “When lit” mean on a slot machine?
“When lit” is a casino term indicating that a payout, feature, or condition applies only while a lamp or on-screen indicator is illuminated. It’s common on reel glass and video UIs. If the light isn’t on, normal paytable rules apply and the special benefit won’t trigger.
How do I tell if a “When lit” feature is active?
The machine will show a lit bulb icon, a glowing label, or a highlighted area near the relevant symbol, payline, or bonus. Many games also flash a sound/animation. Always cross-check the paytable and rules panel to see exactly what becomes active and under which bets or states.
Can “When lit” mean max bet is required?
Yes. Some lights illuminate only at maximum credits or specific stake levels, unlocking extra lines, multipliers, or progressives. Read the paytable and help screens for the exact “When lit” definition. For guidance on which stakes activate features, 101RTP reviews and tools outline requirements and typical value trade‑offs.
Is “When lit” used on modern online slots too?
Absolutely. While classic cabinets printed it on reel glass, online and video slots show “When lit” as UI badges, glowing frames, or toggles like “ON.” The concept is identical: the specified benefit applies only while the indicator is active, and stops as soon as the light turns off.
Do “When lit” indicators change RTP or volatility?
The core RTP doesn’t usually change; the paytable assumes the feature’s average uptime. However, “When lit” can alter volatility during active periods by boosting pays or enabling jackpots. Expect bigger swings while lit. Check game rules for any RTP ranges tied to bet settings or optional features.
Why does the When lit meaning matter for players?
It prevents mistaken expectations about what is eligible to pay. Knowing the When lit meaning helps you time wagers, avoid chasing unavailable features, and budget bankroll for active windows. For practice reading these signals, 101RTP’s guides and simulators show how “lit” periods impact session risk and bonus clearing.
What is the When lit definition compared to “always pays” rules?
The When lit definition is conditional: the machine pays the stated bonus only when an indicator is illuminated. “Always pays” rules apply regardless of lights. If you don’t see the light, assume base rules. This clear distinction reduces disputes and helps players plan gambling sessions responsibly.
