Rounding off our half-year reports of best-performing tipsters through the first six months of 2025, we turn our eye towards a handful of services that focus their attention on sports betting outside the two mainstream markets of horse racing and football.
Just click on the links for more information about each tipster, and for details of any trial deals that are currently on offer.
8th Value80
- 266 volleyball tips, 10.3% ROI, £547 profit
Without ever managing to make it into our monthly rankings, Value80 flies the flag for the niche sport of volleyball after completing a smooth transition since his move from the Pyckio platform.
Five positive months out of six so far this year have been built across a broad range of the most popular volleyball markets, and while the majority of bets have been on the safe side of the moneyline, a 63% success rate has been more than enough to sustain a healthy profit.
7th WadsterTips
- 366 tennis tips, 10.4% ROI, £761 profit
Tennis tipsters dominate this shortlist, kicking off with WadsterTips, who has been a stalwart of the Tipstrr community on and off since late 2017, and has spent the first half of 2025 proving that his popular tennis service continues to provide a realistic prospect of achieving long-term profit from tennis betting.
Since beginning the year with an uncharacteristic drawdown, five straight profitable months have been enough to maintain 10% growth over the last six months, thanks to a 47% win rate that has been all the more remarkable for recommending average odds above 6/4 across a wide range of tennis markets.
6th Discovery Tennis
- 156 tennis tips, 11.8% ROI, £368 profit
Having first appeared on Tipstrr last November, Discovery Tennis has been making steady progress and finally caught the eye when May’s 52% ROI earned him a top four berth on our Best New Tipster leaderboard.
That timely profit spike was reinforced by June’s 20% yield, while 2025’s consistent growth has been built on a 45% win rate at average odds considerably above even money, while a willingness to combine some of those singles into more lucrative doubles has helped keep this year’s gains above the 11% mark.
5th OldGuy13
- 333 tennis tips, 12.7% ROI, £843 profit
In fifth place, the tennis service of OldGuy13 might well have topped this leaderboard, but for June’s slight dip taking the edge off an impressive sequence of five profitable months on the bounce that have nevertheless accrued a healthy 12.7% gain so far this year.
As another welcome Pyckio import, OldGuy13 focuses almost exclusively on extracting value from the ATP circuit, exploring all tennis markets to find the best value, and that mixture of diligence and expertise has been rewarded with a 57% win rate at better-than-even-money average odds.
4th Anna Nass
- 207 tennis tips, 14.1% ROI, £584 profit
After winning our monthly Best Tipster accolade twice in 2024 and enjoying top-7 appearances in February, March, April and June this year, the proven tennis service of Anna Nass is enjoying a purple patch of form just as the tennis circuits reach their bumper summer period.
A selective output of around 8-12 tips per week should appeal to those with more moderate betting appetites, while a sustained 40% win rate at average advised odds only just shy of 2/1 indicates a betting strategy and an eye for value designed to provide long-term growth.
3rd Jack Of All Trades
- 297 tennis tips, 15.9% ROI, £946 profit
While his name might state that he’s a Jack Of All Trades, anyone following this service since the turn of the year will be happy that he appears to be a master of his preferred tennis betting markets.
The service’s multi-tiered staking plan is designed to reflect betting confidence in each carefully-selected tip, which has in turn helped to maximise profits and mitigate losses very effectively to keep his profit line climbing throughout the first six months of 2025.
The tipster’s knowledge of his markets is illustrated by his itemised profits over the last three months, with Match Winner (19%), Asian Handicap Games (53%). Asian Handicap Sets (22%) and First Set Winner (51%) all combining their individual market returns to maintain an impressive 15.9% overall yield from 290+ tips so far this year.
2nd Tron
- 208 basketball tips, 18.6% ROI, £775 profit
Occupying the runner-up spot, Tron is basketball’s sole representative on this leaderboardboard, and he has done his preferred sport proud by kicking off his Tipstrr career with six consecutive profitable months before taking a well-earned break at the end of the 2025 season.
As stated on his profile page, the service follows a simple premise - predominantly Asian Handicap bets, all recommending the liquidity of Pinnacle’s markets, and all at recommended odds hovering either side of the even-money line.
With a lowest monthly ROI of 15%, Tron clearly has found a formula for achievable long-term profitability, boasting a very palatable 18% ROI since the turn of the year from a manageable supply of 8-12 selections per week.
1st Serve & Win
- 312 tennis, 18.8% ROI, £1,176 profit
Although only launching at the beginning of the year, Serve & Win has wasted little time carving out a niche as one of the most reliable tennis tipsters on the platform.
Five straight months of double-digit growth were rewarded with a berth among April’s Best New Tipsters (29% ROI), before May’s 22% yield saw him rubbing shoulders with our more established performers on our main leaderboards.
Always willing to back the underdog in his preferred Match Winner market, this year’s sustained 43% win rate has been all the more impressive for his 312 tips averaging advised odds in excess of 7/4, making him one to watch for anyone looking for a tennis tipster with an achievable edge.
We hope there's enough quality tipsters in the above list to pique your interest in alternative sports betting, and we're confident that here at Tipstrr we offer enough varied services to suit most sporting tastes.
Well done again to Serve & Win for an impressive performance through the first half of the year, and we hope to see him and others featuring again in our Best Tipster rankings throughout the remainder of 2025.
