NetBet's welcome free bets can be turned into withdrawable cash through matched betting on an exchange: the qualifying bet is low-risk when done correctly, but only the tennis in-play free bet covers cleanly.

Quidsy lists NetBet for that route, not as a recommendation to bet for entertainment. The qualifying bet is covered on the exchange, so whatever the result you lose only a small, predictable amount. The free bets are then a conversion question: the tennis in-play token is the cleanest one, while the football bet-builder, football accumulator and horse-racing accumulator convert to less. The careful part is following NetBet's settlement, odds, token-type and expiry rules closely enough that the matched-betting maths still works. If you want a bet for entertainment rather than a methodical routine, or you will not follow the steps closely, skip it.
