The biggest priority when it comes to any Bet £10 Get £40 sign-up offer is flexibility. A betting offer can look wonderful but if it is limited by qualifying requirements, it quickly loses its lustre.

A qualifying bet can be summed up in two parts, the markets allowed and the minimum odds.

If the qualifying bet is limited to a specific bet type (an acca) or a sport (football, racing etc), then that narrows down the scope of options and by default can make it tougher to pick a winning outcome, especially if it's not the bet type or sport you wish to punt on.

However, if the minimum odds requirements are low, then players have more choices. For instance, SpreadEx only requires odds of 1/2 (1.5) or higher which is very good for punters.

There are of course other factors to consider outside of the betting markets, with ongoing promotions, payment methods and betting apps all considered when picking out the best option.

With all this in mind, our currently recommended Bet 10 Get 40 bookmaker is CopyBet. CopyBet's promotion is straightforward, with 5 x £10 free bets and no market limits. That is countered by longer qualifying odds at 9/10 (1.9), however, CopyBet offers an excellent sportsbook and a great app too, to make the players betting experience A1.

Wagering rules can require players to stake their free bets on several occasions. So, If a player receives £40 in free bets and a turnover of 2x is required, then players would have to make £80 of bets (2 x £40) before being able to withdraw winning funds. Thankfully, current Bet 10 Get 40 offers only require a 1x turnover, meaning that if you win, you keep the funds.

High Qualifying Odds:
The minimum odds on a qualifying bet can greatly improve your chances, with the lower the better. CopyBet asks for 1/2 (1.5) odds or higher, compared to BetVictor's Evens (2.0) or more. It may not be a huge difference, but it opens the door to more obvious and potentially winnable bets from the start.

Ineligible Payment Options:
if you are depositing using a bank/debit card then all is good to go, but those looking to use an alternative payment method should check the T&Cs of the bonus on offer. E-wallets such as Neteller and Skrill are regularly blocked from the qualifying terms.

Quickly Expiring Offers:
Most bookmakers allow at least 7 days from signing up to claim the bonus offer and a minimum of 7 days from the awarding of the free bets to use them, so make sure you have enough time to qualify and use the bets, or you will miss out!

Waiting For Those Free Bets:
Some promotions offer free bets once the qualifying bet has been made, however, some offer free bets once the qualifying bet has settled. So long story short, don't bet on the next World Cup winner or you will be waiting a while for those freebies!!

Having To Bet On Markets You Don't Want To
Some of the Bet 10 Get 40 offers require players to bet on specific markets (BetVictor), which can be a pain if it is a sport you don't know/like. This is also the case with market types, with SpreadEx requiring players to bet on spreads and fixed odds markets. Check the T&Cs before sign-up to see how your free bets are split.

Is It A Free Bet or Free Bets?
All of the Bet 10 Get 40 offers currently available split the £40 into at least four separate amounts, however, there have been occasions where one single free bet is offered. Having all the eggs in one basket is never ideal for betting, so always make sure your free bets are split into at least four or more ideally.

UK punters love how simple and easy "Bet & Get" offers are, especially when there are no wagering requirements to worry about, making those free bet wins even more satisfying.

Although Bet £10 Get £40 is at the higher echelon of free bet welcome bonuses, many of them do ask players to use their free bets on specific sports or markets, which can be a little annoying, especially if you don't have knowledge or interest in an event or bet type.

For players who want even more simplicity to their free bets, bonuses such as Bet £10 Get £20 and Bet £10 Get £30 should not be ignored, as many offer a handful of free bets which can be used on any market and with a minimum odds stipulation only.
