If you didn't play before the TGE probably you'll be able to buy some tokens later so no worries.
There's still a lot of time to wager as normal and earn points that count towards your share of the airdrop during TGE. Airdrop 1 is of course divided in 8 milestones and we are just in number 2. It's going to be a total of 200m Reroll tokens in airdrop 1, so there's still a lot of time to get these tokens, if you are interested in them. There is also going to be Airdrop 2, though that's TBD.
It is certainly good that Reroll is giving free tokens to their users.
It is not free per se. You'd have to wager normally and earn points to get a share.
As always, it is not recommended to wager more just in order to chase airdrop because we have no idea how much we will get from the airdrop in real value.
Not only here but also in other casinos where there is similar token program launch, although we have seen some successful casino tokens but there were also some failed casino tokens.
In other words, the success of other casino tokens cant be used as a reference for gambler to wager more.
Taking a part is not that bad as well but it should not be something to chase, casino token airdrop should be taken as a side bonus only so it will be great if it will be something valuable in the future but we wont be that sad if the opposite happen eventually.
