Sports betting on your phone, from the Sports tab to the slip

A sports bet at decimal odds returns your stake times the price, and the stake is already inside that figure. Profit is what is left after you take the stake away. On 13.10 the Champions League match Lens v Sporting CP was priced 2.54 / 3.75 / 2.61, and Arsenal v Lille 1.21 / 6.6 / 14.0.

You can also read a price as the bookmaker’s view of the chances: 1 divided by the odds. For the Lens v Sporting draw that is 1 / 3.75 ≈ 26.7%, and for Sporting 1 / 2.61 ≈ 38.3%. Those are the prices’ opinions, not facts about the match.

Tapping a price drops that pick into the betslip, and on 13.10 this worked without logging in. The slip then offers three tabs, Single, Multiple and Series, which are the three types of bet most sportsbooks build around.

Single bet: one pick, one result

A single bet stands on one outcome only. If you add two picks and stay on the Single tab, each is staked and settled on its own, so a loss on one does not touch the other. For a first online sports betting session on a phone, singles are also the easiest to check afterwards in Bet history.

Multiple: every leg has to win

A multiple, also called an accumulator, joins your picks into one bet and multiplies the odds. Three legs at 1.65, 2.20 and 1.90 make 1.65 × 2.20 × 1.90 ≈ 6.90, so ₦1,000 would return about ₦6,897 if all three land and nothing if one fails.

Short prices do not make a multiple safe. Five favourites at 1.25 each come to 1.25 multiplied five times ≈ 3.05, and 1 / 3.05 is about 32.8%: by the bookmaker’s own numbers, that slip fails about two times in three.

The slip on 13.10 showed an accumulator win bonus with the line “Add 4 more events to get a 7% win bonus”, and steps of 7%, 9%, 10%, 12% and 15%. It did not say whether the percentage is added to the profit or to the whole return, so read the “Bonus” field in your own slip before you count on it.

Series: several small multiples at once

A series splits your picks into all the smaller multiples of a chosen size. Four picks in a “doubles” series make six doubles; at ₦250 each the slip costs 6 × ₦250 = ₦1,500. Two winning picks out of four still return one double. We did not record which series sizes 1win offers.

Every sportsbook adds a margin to its odds, and you can work it out from the three prices of one match. Add up 1 / odds for home, draw and away; the amount above 100% is the margin.

With the 13.10 prices, Lens v Sporting gives 1/2.54 + 1/3.75 + 1/2.61 = 104.4%, a margin near 4.4%. Arsenal v Lille gives 1/1.21 + 1/6.6 + 1/14.0 = 104.9%, near 4.9%. On 14.10 we ran the same sum on the 1X2 prices of 10 top matches: the average came to about 4.5%, from 3.7% to 5.0%. That is our arithmetic, not a rate the site publishes for the whole book.

The margin is built into the price; it is not a fee taken from each stake, and a single still wins or loses in full. It matters in sportsbook betting when you compare the same match across sportsbooks, because a smaller margin leaves you a slightly better price.

You need to be 18 or over, with an account on a +234 number and naira in the balance; funding the balance from a wallet app has the cashier steps on a phone. Rules on sport betting also differ from state to state, which our state-by-state guide to betting rules sets out.

Football holds most of the list, so its markets have their own page on football markets read on a small screen. If a friend sends you a slip as a code, the guide to rebuilding a friend’s booking code by hand shows how to copy the picks.
