It looks like you’re referring to a **deposit bonus** offer — possibly in an online casino, sportsbook, or gaming site.
A common interpretation of “deposit slot 20 bonus 30” is:
**If you deposit 20 (units of currency, e.g., $20), you get a 30 bonus for slot games.**
This could mean:

– You deposit **$20** → you get an extra **$30 bonus funds** (total $50 to play with).
– Usually such bonuses come with **wagering requirements** (playthrough requirements) before you can withdraw winnings.
– The bonus is often restricted to **slot games** (not table games or live casino).

### Important things to check:
1. **Wagering requirement** – e.g., 30x bonus means you must bet $900 before cashing out.
2. **Game weighting** – Slots often count 100%, other games less or 0%.
3. **Maximum bet limit** while using bonus funds.
4. **Time limit** to complete wagering.
5. **Payment method exclusions** – some deposit methods may not qualify.

If you’re asking whether this is a good deal, it depends on the terms. A **150% match bonus** (deposit $20 → get $30 bonus) is fairly generous if the wagering is reasonable.
