They have it listed under the "rewards" menu item. I can't paste the URL because the site is framed.
This is going to sound super critical, and it sort of is. But I do like the site. In fact when I was doing faucets just to get my feet wet with BTC, I stopped using all of them after a week, except for two including freebitco.in simply because I like how the site is setup an it's very casual to claim every so often. I keep hoping for a high roll but nothing but the lowest so far.
That being said, I agree with Jonar21 that there will be very few redeems because most of them are simply next to impossible to achieve. For example: The primary reward they list at the top of the rewards page is option to "ENCASH YOUR POINTS" which means you can trade in 1 reward point for 13 satoshi. The problem however is that there is a minimum redeem of 100,000 rewards points to use the encash. Anyone failing to do the math might be lured by the promotion, but the reality is, it would take the average user 5.7 years to earn that many reward points, and this is assuming that the user rolls every hour of every day... for 5.7 years. 2 reward points every hour = 48 points per day. 48*365=17,520 (points per year) and 100,000/17,520 = 5.7 years.
You get one RP for each roll of a referral too, but you have the same problem of lack of consistency, no one is going to be able to roll every hour of every day for x number of months or years so the accumulation of RP by referrals probably wont be much help towards earning 100,000 RP.
And then you earn 1 point for every 6500 you gamble, or another way of putting it, you earn 13 satoshi for every 6500 satoshi that you eventually lose.

Seriously, no one will ever encash 100,000 rp.
There are other ways to redeem RP listed below the encash option. Such as an APPLE IPHONE 6S (128 GB) for 12,653,333 RP (733 years). There is a way to multiply the amount of RP you get per roll, but this cost RP and it only increases your multiplier for 24 hours. For example, if you spend 18 RP then you get 1 additional RP per roll. The only way to make this profitable is to play 19 hours in one day, and then you only profit by 1 RP. So this too is not worth it. There are other higher multipliers, but you have to also spend more RP to activate them. I can't imagine anyone rolling more than 6 times a day which means you are at your keyboard 6 hours which means you LOSE RP doing this.
The only redeem option I like
I do like the bonus BTC rewards. By spending RP you can increase how much you get per roll. For example, spend 48 RP and you get 10% more Satoshi per roll for the next 24 hours. 240 RP for a 50% increase is probably the single best reward in terms of time. You actually earn the same amount regardless of which one of these rewards you choose, but 50% for 240 saves you time because if you do the 10% for 48 then you have to be more active on the site for 5 days instead of just active on the site for 1 day to earn the same BTC bonus. There is still a problem with this reward though because there is no incentive to hold out for the 100%, 500%, or the 1000% because the bonus per RP is the same for all. This can be seen in this quick chart which assumes a base faucet roll of 340 Satoshi (you can enter any value and the result is the same, the bonus per RP does not change):

To give users an incentive to go for a higher % bonus, the website would have to reward a higher BTC per RP for this specific option. Rolling the faucet for 340 Satoshi every hour with an increase of .7 of 1 Satoshi for 6 hours = 4.2 Satoshi per RP. This seems low. If the encash option did not have a minimum, then at the very least, you could earn 13 satoshi per RP and not have to roll every hour for 6 hours. So, yes I'm very critical of this RP system simply because it seems next to impossible to encash, etc.
I think the Lottery is a much better lure for traffic to the site.
I don't think the rewards are that difficult to achieve, We have already had a few people encash a few hundred k points each and a few more who have collected 1 million+ in points. By using your RP strategically it is possible to gather a much larger amount and then use that to increase your free play bonus by 1,000%. I made the system so that people would have to put more thought into maximising their rewards rather than just playing the boring faucet all day.
PS: Also, you get 1 point for wagering 6,500 satoshi (even at odds for 1.01), not for "losing" that amount.
As for people asking about winning the lottery, if I remember correctly quite a few people had posted about winning it here: https://bitcointalksearch.org/topic/freebitcoin-200-freebtcwin-lambo02btc-dailyjackpot32500-wager-contest-319540
People post about winning the lottery sometimes and then a month or two passes and then other start asking why nobody posts about winning the lottery and then some start throwing accusations that the lottery is a scam.
I stated this earlier but if someone can figure out a way to implement a provably fair lottery with a variable number of tickets given out each round, I would be happy to implement it. So far I haven't been able to figure out how to do it myself.
