Mega Ball is Evolution Gaming’s lottery-bingo hybrid — you buy cards filled with numbers, the host draws 20 balls, and you win based on how many lines you complete on your cards. The twist: a final Mega Ball draw can multiply your winning lines by up to 100x. It’s the closest thing to a lottery in the live casino space, with multipliers that can turn a small win into a life-changing payout.
How Mega Ball Works
Step 1 — Buy cards. Purchase between 1 and 200 bingo-style cards. Each card is a 5×5 grid of numbers from 1 to 51, with the centre square free. Cards cost a fixed stake each.
Step 2 — Ball draw. 20 balls numbered 1–51 are drawn randomly. Numbers that appear on your cards are automatically marked off.
Step 3 — Mega Ball. A final 21st ball — the Mega Ball — is drawn. A random multiplier between 5x and 100x is assigned to the Mega Ball round.
Step 4 — Scoring. If the Mega Ball completes a line on your card, that line’s payout is multiplied by the Mega Ball multiplier. Lines completed before the Mega Ball pay standard rates.
Winning and Payouts
Payouts are based on the number of complete lines (rows, columns, diagonals) on a single card:
| Lines Completed | Standard Payout | With Mega Ball (×multiplier) |
|---|---|---|
| 1 line | 1x | 5x–100x |
| 2 lines | 5x | 25x–500x |
| 3 lines | 50x | 250x–5,000x |
| 4 lines | 250x | 1,250x–25,000x |
| 5 lines | 1,000x | 5,000x–100,000x |
| Full house | 1,000,000x | Jackpot tier |
The Mega Ball multiplier only applies to lines that the Mega Ball itself completes. Lines finished during the first 20 draws pay the standard rate regardless.

The House Edge
The house edge in Mega Ball is approximately 3.5–4%, in line with other Evolution game shows.
The high variance of the game — created by the Mega Ball multiplier — means your session results can vary dramatically. Most rounds result in a loss or small recovery. Occasionally a Mega Ball multiplier lands on multiple completed lines and produces a large payout.
Key point: The house edge is constant regardless of how many cards you buy. Buying more cards increases your chance of having a winning card in any given round, but does not improve your expected return per unit staked.
How Many Cards Should You Buy?
More cards = more coverage of the 1–51 number pool = higher chance of completing lines = higher chance the Mega Ball completes a line on at least one card.
Diminishing returns apply. The jump from 1 card to 10 cards significantly increases your win rate per round. The jump from 50 cards to 100 cards adds much less additional coverage per card, because numbers start to overlap.
Practical approach:
- 5–20 cards: Balanced play — meaningful coverage without rapidly multiplying your stake per round
- 50+ cards: High stakes, high volatility — suitable if you’re specifically targeting a Mega Ball multiplier event
- 1–2 cards: Casual play — low cost per round, high variance, rare wins
There is no “correct” number of cards that improves expected value. The choice is purely about risk tolerance and session length.

The Mega Ball Multiplier: What to Expect
The Mega Ball multiplier is assigned randomly each round. Approximate distribution:
| Multiplier | Frequency |
|---|---|
| 5x–10x | Most common |
| 20x–50x | Occasional |
| 100x | Rare |
The multiplier is revealed after the 20 standard balls, just before the Mega Ball is drawn. If you have lines that could be completed by the Mega Ball, this moment determines whether you get standard or boosted payout.
Strategy Summary
Mega Ball is a lottery-style game — outcomes are random and no playing decisions affect probability. The only choices are:
- How many cards to buy: More cards = more exposure to each round, more cost, more chance of hitting a Mega Ball multiplier.
- Session budget: Set a fixed number of rounds or total stake before you start. Mega Ball can be fast and it is easy to overbuy cards without noticing.
- Accept variance: The Mega Ball multiplier is what makes this game compelling. Most rounds will be losses or small wins. The game is designed around the occasional large multiplier event.
