Esports · Mobile Legends: Bang Bang
Mobile Legends: Bang Bang is a 5v5 mobile MOBA with its strongest pro scenes in Southeast Asia. Bookmakers price its top events: the MPL leagues, the M-series world championship and the Mid Season Cup at the Esports World Cup. Markets are thinner than for PC titles, mostly series winner, game handicap, total games and a few objectives.
This page explains those markets, shows how series length changes the favourite's chance, and lists the bookmakers we rank. Coverage differs a lot between bookmakers, so check the MLBB market list before you deposit.

Short answer
You bet on the series, a single game or an objective such as the first Lord. Top MLBB events play best-of-five and best-of-seven series, so the stronger team is favoured more than in a single game: with a 60% chance per game it wins a BO7 71% of the time.
Markets Example odds
The markets most bookmakers offer on MLBB, with example odds for a BO5 between two evenly matched sides.
| Market | You bet on | Example odds | Margin | What it means |
|---|---|---|---|---|
| Match winner | Who wins the series. | 1.57 / 2.36 | 5.7% | the cheapest MLBB market in the example. |
| Game handicap | The favourite −1.5 games must win 3–0 or 3–1 in a BO5. | 1.95 / 1.80 | 6.4% | a longer price for a clearer win. |
| Total games | Over 3.5 if the BO5 goes to a fourth or fifth game. | 1.56 / 2.34 | 6.4% | a bet on a close series. |
| Game 1 winner | Who wins the first game only. | 1.61 / 2.23 | 6.5% | the draft decides more than series form. |
| First Lord, game 1 | Which team kills the first Lord. | 1.68 / 2.06 | 7.5% | usually the team ahead at that point. |
| Correct score | Exact series result in a BO5. | 3.95 / 4.14 / 5.12 / 7.25 / 5.80 / 6.69 | 13.0% | the highest margin in the example. |

Series maths
If each game is independent, the series chance follows from the chance per game. Move the slider to see the effect.
BO3 = p² × (3 − 2p)
BO5 = p³ × (10 − 15p + 6p²)
Example, p = 0.60: BO5 = 0.683
| Per map | BO1 | BO3 | BO5 | Fair odds BO3 | BO3 vs BO1 |
|---|---|---|---|---|---|
| 50% | 50.0% | 50.0% | 50.0% | 2.00 | ±0.0 pp |
| 55% | 55.0% | 57.5% | 59.3% | 1.74 | +2.5 pp |
| 60% | 60.0% | 64.8% | 68.3% | 1.54 | +4.8 pp |
| 65% | 65.0% | 71.8% | 76.5% | 1.39 | +6.8 pp |
| 70% | 70.0% | 78.4% | 83.7% | 1.28 | +8.4 pp |
| 75% | 75.0% | 84.4% | 89.6% | 1.19 | +9.4 pp |
| 80% | 80.0% | 89.6% | 94.2% | 1.12 | +9.6 pp |
Pure maths: games treated as independent with the same chance p.
