1Win adds a percentage on top of any multiple bet that wins with five or more selections — the net win itself gets topped up automatically, with the exact percentage rising as more legs are added to the bet. It's a reward for building bigger accumulators rather than for depositing, and it applies on top of whatever the bet would have paid out on its own.
The Scale, From 5 Selections to 11+
| Selections in the multiple | Bonus on net win |
|---|---|
| 5 | 7% |
| 6 | 8% |
| 7 | 9% |
| 8 | 10% |
| 9 | 11% |
| 10 | 12% |
| 11 or more | 15% |
For most of the scale, each additional selection adds exactly one percentage point — 7% becomes 8%, then 9%, then 10%, climbing steadily in lockstep with the bet slip. The pattern breaks at the top end: going from 10 selections to 11 jumps three points at once, from 12% straight to 15%, and every multiple bet with 11 or more selections earns that same 15% regardless of whether it has 11 legs or 20. Past that point, adding further selections doesn't increase the percentage any further, even though it does increase how difficult the bet is to actually win. The structure rewards players for building past the five-selection floor early on, then flattens out once an accumulator is already long enough to be genuinely hard to land.
Here's how that plays out on a slate of matches actually on 1Win's pre-match board:
| # | Match | Selection | Odds |
|---|---|---|---|
| 1 | Dynamo Moscow — Krasnodar | Dynamo Moscow to win | 2.60 |
| 2 | Baltika — Dynamo Makhachkala | Baltika to win | 1.90 |
| 3 | Barcelona FC — Al Ahly Cairo | Over 4.0 total goals | 1.78 |
| 4 | Atletico Madrid — Malaga | Atletico Madrid to win | 1.36 |
| 5 | Celtic — LASK Linz | Celtic to win | 1.75 |
| 6 | NEC Nijmegen — Bodo/Glimt | Bodo/Glimt to win | 2.35 |
That's six selections across six different matches and a mix of bet types — outright winners alongside a total-goals pick — which lands the multiple on the 8% tier. Multiply the six prices together (2.60 × 1.90 × 1.78 × 1.36 × 1.75 × 2.35) and the combined odds work out to roughly 49.18. A $50 stake on that multiple, if every leg comes in, returns a net win of $50 × (49.18 − 1) = $2,409 before any bonus is applied. The 8% bonus is calculated on that $2,409 win, not on the stake or the final payout, adding roughly $192.72. The total credited to the account once the bet settles is the original $50 stake, plus the $2,409 win, plus the $192.72 bonus — a little over $2,651 in total.
It's worth seeing what that same $2,409 win would have earned at other points on the scale, holding the win amount constant to isolate what the tier itself changes:
| If this win had come from | Tier | Bonus on the $2,409 win |
|---|---|---|
| A 5-selection multiple | 7% | $168.63 |
| A 6-selection multiple (the example above) | 8% | $192.72 |
| A 7-selection multiple | 9% | $216.81 |
| A 9-selection multiple | 11% | $264.99 |
| An 11+-selection multiple | 15% | $361.35 |
The stake, the combined odds, and the resulting $2,409 win could stay identical across all five rows — only the number of selections used to reach that win changes, and it alone moves the bonus from $168.63 to $361.35 on the exact same underlying result. Swap in a seventh selection from the same board and the tier moves to 9%; drop to five selections and it falls to 7%. The bonus dollar amount still depends heavily on how big the win itself is, but which percentage applies is decided purely by how many selections are in the bet.
What Actually Drives the Bonus
Two separate things shape the final bonus amount, and it's easy to conflate them. The percentage is set entirely by selection count — a 6-leg multiple always sits at 8%, whether its combined odds are 15 or 150. The dollar value of that percentage, on the other hand, is driven by the size of the net win, which depends on the stake and the combined odds together. A small stake on long odds and a large stake on short odds can land on the same percentage tier while producing very different bonus payouts in real terms — a $10 stake on the same six-leg, 49.18-odds multiple above would return a $481.80 net win and a $38.54 bonus at the identical 8% rate, next to the $50-stake example's $192.72. Same tier, same percentage, very different dollar outcome, purely because the stake was different.
That separation also explains why chasing a higher tier isn't automatically the better move. A five-selection multiple with genuinely long odds can produce a bigger bonus in absolute terms than an eleven-selection multiple built around short-priced favorites, even though the second one sits on the higher 15% tier — the tier decides the rate, not which bet ends up worth more.
The Boundaries of the Offer
Four-selection multiples and smaller don't qualify for any bonus percentage at all — five is the floor, and nothing about odds or stake size changes that; a 4-leg accumulator at extremely long combined odds still earns nothing extra under this offer. At the other end, the scale caps out at 15% once a multiple reaches 11 selections, and building an even longer accumulator beyond that doesn't push the rate any higher, even at 15 or 20 selections. Throughout the scale, the bonus is always calculated against the net win amount specifically, not the full payout that includes the returned stake — a distinction that matters most on bigger stakes, where the returned stake itself can be a meaningful chunk of the total payout figure shown on the bet slip.
