It looks like you’re referring to **slot machines** or **casino bonuses**, but your message is quite short.
Let me break down what you might mean:
—
**1. If you mean “Slot 20, Bonus 30” in a casino context:**
– This could refer to a **slot machine** where you bet 20 (credits/coins) and get a bonus round worth 30 (credits/free spins/payout).
– Or it could be a **casino bonus offer**: deposit 20, get 30 bonus (like a 150% match bonus).
—
**2. If you’re talking about a specific game or promotion:**
Sometimes slot games have features like “Bet 20, trigger bonus with 30 free spins” or “Min bet 20 to qualify for bonus round.”

—
**3. If you’re asking whether it’s a good deal:**
– In casino bonuses, a “deposit 20 get 30 bonus” usually means you put in 20 of your own money, and the casino gives you 30 bonus funds (often with wagering requirements).
– In slot play, betting 20 per spin for a chance at a bonus round is a medium-to-high stake in some games.

Could you clarify what exactly you’re asking about?
For example:
– Is this a casino bonus offer you saw?
– Is it a slot machine paytable description?
– Or are you asking if it’s worth playing?
