How We Review Sportsbooks

Every sportsbook we review gets a 0-5 score computed from seven weighted dimensions. The weights below are public, the tests are reproducible, and the data is logged. We don't accept payment to change scores.

The seven dimensions and their weights

Dimension	Weight	What we measure
Tennis odds quality	30%	Vig vs Pinnacle benchmark across 50 random matches
Tennis market depth	15%	Count of bet types: ML, set spread, totals, set betting, props, live, futures
App + UX	15%	iOS/Android app rating, web speed, live-betting interface
Payout speed	15%	Real test: deposit, win bet, withdraw — measured in hours
Bonus real value	10%	Welcome bonus after rollover and time limits — actual EV
Customer support	10%	Live chat response time + email turnaround across 5 test tickets
Licensing & compliance	5%	Regulator quality (UKGC > MGA > Curaçao), self-exclusion tools, audit trail

1. Tennis odds quality (30%)

Single biggest weight because it determines whether you make money long-term. We pull moneyline odds for 50 random ATP/WTA matches and compute the implied probability spread (vig) for each.

Pinnacle is the industry benchmark at ~2-3% vig. We compute each book's average vig and grade on a curve:

• ≤ 3% vig → 5.0
• 3-4% vig → 4.5
• 4-5% vig → 4.0
• 5-6% vig → 3.5
• 6-7% vig → 3.0
• > 7% vig → 2.0 or lower

Vig is computed: (1 / decimal_odd_a) + (1 / decimal_odd_b) - 1. Lower is better — less margin for the book, more for you.

2. Tennis market depth (15%)

We count distinct tennis bet types offered:

• Moneyline
• Set handicap (-1.5 / +1.5 sets)
• Total games (Over/Under)
• Set betting (exact set score)
• First set winner
• Total aces (player props)
• Total double faults
• Tiebreak yes/no
• Outright tournament winner
• Live (in-play) markets — counts as +2 if available
• Specials and request-a-bet

10+ markets → 5.0 · 7-9 → 4.0 · 4-6 → 3.0 · <4 → 2.0.

3. App + UX (15%)

We install both iOS and Android apps, run 10 sessions each, and grade on:

• Time-to-bet (homepage → bet placed) — < 30s = full marks
• Live point graph quality — does it show momentum? service stats?
• Cash-out functionality availability and speed
• Bet history accessible without re-login
• App Store rating (weighted: number of recent reviews)

4. Payout speed (15%)

We make real deposits, place real bets, win some, and time the withdrawal cycle. Measured for each major method:

• e-wallet (Skrill, PayPal, Neteller): < 24h = full marks
• Pix (Brazil): < 1h = full marks
• Card refund: < 5 days
• Bank transfer: < 7 days

Payout speed scores are time-weighted across methods that the book offers in your country.

5. Bonus real value (10%)

Every welcome bonus has a sticker price ("100% up to $200!") and a real value after rollover, time limits, and minimum odds. We compute:

real_value = sticker × clearance_probability(rollover, min_odds, time_limit)

A "100% to $500" bonus with 5x rollover at minimum -200 odds is worth maybe 20% of sticker. A "$50 free bet" with no rollover is worth ~70%. We score real value as a ratio of typical industry baseline.

6. Customer support (10%)

We open 5 support tickets per book over a 30-day window — mix of mundane (deposit question) and complex (disputed bet settlement). We measure:

• Live chat first-response time (median)
• Email response time (median)
• Resolution rate without escalation
• Whether agents understand tennis (some books outsource and the agent has no idea what a tiebreak is)

7. Licensing & compliance (5%)

Regulator tier breakdown:

• Tier 1: UKGC, MGA (Malta), AAMS-IT, NJ-DGE — 5.0
• Tier 2: SECAP-BR (Brazil), state US licenses, German/Spanish — 4.0
• Tier 3: Curaçao, Antigua — 2.5
• Unlicensed offshore — 0.0 (not reviewed)

We add bonus points for self-exclusion tools (GAMSTOP, GAMBAN integration), deposit limits, and proactive responsible-gambling messaging.

Things that don't move our score

• Sponsorships of teams or players — irrelevant to the user experience.
• Ad campaigns — bigger marketing budget ≠ better book.
• Affiliate commission rate — we firewall this from editorial.
• Logo design / brand recognition — visual identity isn't a product feature.

Re-review cadence

Every book is re-tested every 90 days. Score changes > 0.3 trigger a rewrite of the review with a date-stamped change log. If you spot something that contradicts our rating, email editorial@tenisedge.com.
