If you only read year averages, Rainbet beat Duel. Ten against eight, worldwide, 18 August 2026, same five casino keys. That sentence is true and almost useless.
Rainbet sat on 3 until June. Then the weekly relative-interest line went 76, 62, 82, 100, 77, and back to 3. That June block is why the year average lands at 10. Duel's year is an 8 built from a long stay at 1-2, a climb from March, and a 53 in the week of 31 May. Two different shapes. One noisy month versus a slower rise. The average erases the shape.
BC.Game, on the same key, never left 1 to 3. Roobet lived at 4. Stake lived in the mid-20s to high-30s and still owns the year at 29. The June story is Rainbet's. It is not a five-book reshuffle.
What Rainbet was selling while the line went vertical
The comparison sheet, same August pass, prints Rainbet as RBGAMING N.V., Anjouan. Casino and sports on one track. Two first-deposit doors, one with a 40x lock. Rakeback every ten minutes. Browser only. Pre-match, live, cash out on selected events, early football payout.
That is a product a spike can sell: a timer on the rake, a lock on one welcome path, same island as Duel. It is not Duel's product. Duel's welcome cell is "no match, instant rakeback as cash, sports tickets share the pot." If June traffic arrived for a 40x door, it arrived for a different deal than the one the 13 August Duel review is scoring.
Duel's sports cell on the same sheet is "same wallet, 1.96% margin on the review sheet, reviews print 30+ to 50+ sports." Rainbet's is pre-match, live, cash out on selected, early football payout. Both are hybrid books. Only one of them spent June at 100 on a Google key and then disappeared.
Same island, different welcome
Anjouan is not a Duel exclusive. Rainbet is on it too. If you use licence as a shortcut for "safe" or "unsafe," you will file them together and miss the welcome row. One book refuses the match. The other still offers a path with a 40x lock. That lock is the $500-costs-$800 structure in another costume. A June spike does not tell you which door the new accounts used.
Stake, Roobet and BC.Game stayed on Curaçao. Their June lines did not go to 100. Attention and licence are different axes. The 18 August chart is attention.
Why a vanished 100 still belongs next to a Duel review
Because people will quote "Rainbet is bigger than Duel on search" into the autumn. The chart says the year average is bigger. The weekly line says the year was a June event. Duel's 53 was a late-May event. Stake did not need an event.
The Duel Casino Review does not pretend a Trends key is a deposit ledger. It scores the book in front of it: 4.4 overall, 3.2 on licence, 5.0 on rakeback. Use the June spike as a warning about averages. Do not use it as a reason to skip the Anjouan paragraph on either brand.
