BetFury is an online casino, but don't let that put you off if you're not a gambler - it also offers lots of crypto freebies for anyone (like me) who isn't willing to risk their own money. One of those is the 'FunFury Competition', which runs twice a day offering a prize pot of $150 each time. I've worked out a simple strategy to claim some of that.
1. Sign up for a free account
First, you'll need to sign up for a free BetFury account. The good news here is that there's no KYC - so you can put that passport away! The daily FunFury Competition is only open to 'Rank 1' BetFury users, which is basically anyone who hasn't yet wagered a total of $3,000 USDT. So as a new user you're good to go.

2. Understand the rules of the game
You can find the details of the FunFury Competition by clicking on the '$150 FunFury Competition' link under 'Promotions' (which appears on the left-hand vertical menu if you are using desktop). This brings up a window like this:

From here, you can click on 'More details' to bring up the full rules. But to save you a job, here's my attempt to summarise:
The aim of the game is to earn as much 'profit' as possible on FunFury tokens. The more 'profit' you earn, the higher up the winners leaderboard you appear, and the more you win. So the top winner takes home a prize worth $19.50 (made up of $6.50 USDT and the rest in BetFury's own BFG token).

There are 300 places on the leaderboard each time the competition runs, with the 300th ranked player taking home a prize worth $0.045 (0.015 USDT and the rest in BFG).
I put the word 'profit' in inverted commas because FunFury tokens have no real value. They are effectively play money - you can't withdraw or exchange them, and your balance on BetFury is reset every 12 hours (At 4:00 UTC and 16:00 UTC, in line with the competition start times). They are only good for testing out the games on BetFury without risking any real money - and taking part in the FunFury competition, of course.
Basically you will be gambling these worthless tokens to win more of these worthless tokens. The more you can win in that 12-hour period, the higher up the leaderboard you will rank and the more real crypto you will take home. But before you can earn profit on your tokens, you need to have an initial stake.
3. Get some FunFury tokens
There are two ways to get hold of your initial stake of FunFury tokens. You can either spin the FunFury wheel, or claim the FunFury box (or both).
The FunFury wheel is available to spin twice a day (so it runs to the same sort of schedule as the competition). Every spin results in a prize, which could be real crypto such as ETH or BNB - the grand prize is 1BTC.

I've spun it dozens of times and the only real crypto I've ever won is three lots of 500 SHIB, worth less than two cents in total! Every other time I've picked up either 8,000 or 10,000 FunFury tokens to use for the competition. But that's fine, because it's what we need for the next step.

The FunFury box, on the other hand, allows any Level 1 user to claim 100 FunFury tokens every 20 minutes. The box gradually fills up over this time period - once it is full, click 'Withdraw' and complete the CAPTCHA to get your hands on the tokens. (The BFG, BTC and BNB boxes, which pay out real crypto, work in the same way and are well worth doing.)

Now if you are any good at maths, you will see that the wheel pays out more (8,000 minimum) than you can possibly claim from the box in a 12-hour period (3,600 maximum). So my advice to you would be to spin the wheel, get the free FunFury tokens, and move on to the next step. (And if you do happen to get lucky and win some real crypto on the wheel - great! Just try again in 12 hours' time.)
4. Make a big gamble
Now we're going to make a single high-odds bet in the hope of generating a lot of profit and increasing the size of our initial stake. Don't get me wrong, you will probably lose this bet AND your entire stake - in which case you can try again in 12 hours. It seems to me a much more efficient to make one large bet at this stage rather than spending time on lots of small bets and not making it on to the leaderboard anyway.
You can choose any BetFury game you like for this stage, but I prefer 'Dice' as it gives you control over and visibility of the precise odds and potential winnings. Go to the game, choose 'Max' stake (ie your entire 8,000 or 10,000 FunFury tokens) and set a chance to win of say 10%. This will give you a multiplier of x9.8 and a potential profit on win of either 98,000 or 78,400 tokens. (You might expect the multiplier to be 10x but remember that BetFury needs to make a profit on bets over time - this is the so-called 'house edge'.)

Odds of 10% may seem poor, but remember you can spin the Fury Wheel twice a day. So you get 14 spins and 14 attempts at this step each week. It's likely that you will win this bet at least each week. And once you do, move on to the next step.
5. Get ready to generate profit safely
While 98,000 (or 78,400) tokens sounds great, it still isn't enough to get you on to the leaderboard and win some real crypto. But it is a large enough stake to create a profit that will do that.
One key thing about BetFury's concept of 'profit' here is that it only takes into account the tokens you have won, not the tokens you have lost. So you can and should eventually gamble away all of your tokens. But placing another high-odds, all-or-nothing bet here probably isn't the way to go - I'm happy to wait a week to make it on to the leaderboard, but not a couple of months! Instead, what we will do is gamble away our tokens in a way that reliably and safely generates profit until our entire stake is gone.
Sticking with the Dice game, move the slider up so your chance to win is 95%. Set your bet to something like 1,600 and turn on 'Fast' mode (it's the little rocket ship icon towards the top, circled in my screenshot below). Finally make sure you are in AUTO (also circled) - this will continue placing bets for you, one after the other, until you have no stake left or you choose to stop it.

There's one more thing to check: make sure you have selected FunFury as your currency (you can change this using the dropdown at the very top of the page). It would be terrible to accidentally burn through your BFG, ETH or BTC!
6. Generate that profit
Now hit START and wait while your FunFury is slowly gambled away. It may go up occasionally, but the overall trend will be downwards - and, depending on the size of your bet and the amount of FunFury you won initially, it might take an hour or so to gamble away. You can check your 'profit' and your place in the leaderboard at any time by clicking on the '$150 FunFury Competition' window (you probably want to do this in a new tab).
I know I said earlier that the FunFury box isn't worth bothering with compared to the Fury Wheel, but it might be worth claiming at this stage. If you're lucky, it could allow you to make one more successful bet - slightly increasing your total profit and pushing you up a place or two in the leaderboard.
7. Wait and win
Once all your FunFury tokens are gambled away, you should have a profit around 2.5x that of your initial big win. For example, if you initially gambled 10,000 FunFury at 10% odds, winning 98,000 tokens, your profit will now be around 250,000. This should be enough to bag you one of the smaller prizes in the competition.

But you will first need to wait for the competition to come to an end (and while you are waiting, your place may well drop down as other players overtake you). Once the competition is over, BetFury sends all winning players a notification confirming the amount they have won. It looks like this:

So far I've used this strategy successfully twice. The first time that it worked, I used odds of 10% at the 'big win' stage. I ended up winning a small prize of 0.02 USDT and 2.63 BFG. After that, I changed my odds to 5%. It took me longer to get a successful roll, but I then went on to win a larger prize of 0.12 USDT and 15.66 BFG (which means I must have placed in the top 100 players).

Best of luck on BetFury, and please let me know how you get on!
