Tennis has three majors on the calendar between May and September, and 22Bet built an entire promotion around betting on all of them. The Grand Slam tennis balls promotion runs from May 18, 2026 through the close of the US Open in mid-September, rewarding qualifying tennis bets with collectible "tennis balls" that feed into a series of prize draws — three stage draws plus one main draw covering everyone who bet across all three tournaments.
What Actually Counts as a Qualifying Bet
Not every tennis wager during the promotional window earns balls. A qualifying bet needs to be at least 3 USD, placed on a French Open, Wimbledon, or US Open match, and it needs to clear a minimum odds bar depending on bet type: 1.3 or higher for a single bet, or 1.8 or higher combined odds for an accumulator with at least two selections. Totals and handicap bets are explicitly excluded — a correctly-staked, correctly-priced bet on the match winner market qualifies, but the same stake on a totals line doesn't earn anything. Balls are only credited once a bet actually settles, so an open bet sitting in the bet slip doesn't count until it resolves.
How Many Balls a Bet Actually Earns
Balls scale with stake size, but not at a constant rate — the reward table jumps unevenly as the qualifying stake grows:
| Stake | Tennis balls |
|---|---|
| 3 USD | 1 |
| 8 USD | 3 |
| 17 USD | 10 |
| 29 USD | 20 |
| 58 USD | 60 |
| 116 USD | 90 |
| 174 USD | 160 |
| 349 USD | 350 |
| 581 USD | 600 |
| 871 USD or more | 1,000 |
Working out the balls-per-dollar rate at each tier shows the reward isn't linear: a 58 USD bet returns roughly 1.03 balls per dollar staked, while the very next tier at 116 USD drops to around 0.78 balls per dollar before climbing again through the higher tiers. In practical terms, a bettor deliberately chasing maximum ball efficiency would get better value clustering stakes around the 58 USD, 349 USD, or 871+ USD tiers than sitting right at 116 USD. There's no cap on activity either — the rules explicitly state there's no limit on the number of bets placed or balls collected, so five separate 8 USD bets that all settle as qualifying wagers would return 15 balls total (5 × 3), the same as if the rules had capped ball-earning per account rather than per bet.
Why Betting on All Three Tournaments Matters
Balls earned during any single tournament automatically enter that tournament's own stage draw, but reaching the main draw — the one with the Rolex and the iPhone — requires betting on all three majors during the promotional window, not just one or two. A bettor who only wagers during Wimbledon still qualifies for the Wimbledon stage draw, but sits out of the main draw entirely unless they also place at least one qualifying bet during the French Open and US Open windows.
The Main Draw Prize Table
The main draw carries a total pool of 52,277 USD across cash, free bets, and top-tier physical prizes:
| Prize | Winners |
|---|---|
| Rolex Datejust | 1 |
| MacBook Pro M5 | 3 |
| iPhone 17 Pro Max 1TB | 5 |
| 2,323 USD cash | 5 |
| 1,162 USD cash | 10 |
| 465 USD free bet | 15 |
| 349 USD free bet | 20 |
| 116 USD free bet | 50 |
| 46 USD free bet | 100 |
| 23 USD free bet | 200 |
Adding just the cash and free-bet tiers together comes to roughly 52,190 USD, with the remainder of the published 52,277 USD pool accounted for by the three physical prizes — a useful way to gauge how much of the headline figure is actual liquid value versus hardware and luxury items.
What Each Individual Stage Draw Pays
Every one of the three stages — French Open, Wimbledon, and US Open — runs its own draw with identical cash and free-bet tiers, though the physical prizes differ by stage to match each tournament's own timing:
| Prize | Winners |
|---|---|
| 871 USD cash | 10 |
| 349 USD cash | 20 |
| 116 USD free bet | 50 |
| 58 USD free bet | 60 |
| 23 USD free bet | 100 |
| 12 USD free bet | 150 |
On top of that shared structure, the French Open stage adds an iPad Pro 13" M5, PlayStation 5 Pro, and Apple Watch Ultra 3; Wimbledon swaps in a Samsung S25 Ultra, AirPods Max, and Garmin Fenix 8 Pro; and the US Open closes things out with an Apple iMac, Garmin Tactix 7 Pro, and a Meta Quest Pro. A player who wins a physical prize at a stage level and also lands a cash or free-bet prize in that same draw keeps both — the rules explicitly confirm the two prize types stack rather than one overriding the other.
Turning a Win Into Actual Money
Cash and free-bet prizes behave differently once awarded. Cash lands directly in the main account balance, converted at the prevailing EUR exchange rate for the account's currency, and carries no wagering requirement at all. A free bet is a different story — it needs to be used inside an accumulator of at least three selections, each individual leg priced at 1.4 or higher, and it expires just 72 hours after being credited. Missing that 72-hour window means the free bet is simply gone, regardless of how the rest of the promotion played out.
Draw Dates and Account Requirements
The three stage draws land on June 8, July 12, and September 14, 2026 (all 14:00 UTC+3), with the main draw following on September 15, 2026 at the same time. Any prize won is credited within 72 hours of its respective draw, and a physical prize specifically triggers outreach from a project manager via email to arrange delivery. Entry itself comes with account-hygiene conditions worth checking before assuming eligibility: the profile needs a completed full name, an activated mobile number, email, country, and city of residence, only one account per person/family/IP/PC qualifies, and anyone who previously opted out of 22Bet's bonus program is excluded from this promotion specifically as a result of that earlier opt-out.
