Bitcoin Aliens developers have created five apps where users can earn some crypto such as bitcoin, litecoin or bitcoincash.
Explanation of how Bitcoin Aliens works is very simple, like most current apps, Bitcoin Aliens introduces advertising, which makes it possible for us, users, to also earn crypto rewards.
Basically are fun games (some very addictive) where the more we play the more opportunities we have to win prizes, on Bitcoin Aliens website itself you can find this paragraph written by the team itself:
Since 2014 the Bitcoin Aliens games have given away over 1090btc (7+ million USD).
Join over 2.5 million others and start earning bitcoin and other crypto currencies from your phone!
Alien Run, on my point of view is the best of all, with this fun application you can complete missions while earning some bitcoin fractions, it consists of climb levels. To start you can access a tutorial created by the Alien Run team, once you start you will not be able to stop!
On BlockchainGame we will be able to connect blocks (one on top of the other) to win prizes in the form of bitcoin, while more blocks some more opportunities to win satoshis, without a doubt the most addictive game among the five.
Free Bitcoin, FreeLitecoin & FreeBitcoinCash
These three apps are "faucets" to get free cryptocurrencies, the more you play the more chances you have to win. Why? Because every time you make a claim, this box disappears on your next turn, thus reducing the number of boxes and thus expanding the number of possibilities of obtaining greater rewards, we will try to explain briefly what it consists of:
FreeBitcoin is a faucet where you can claim satoshis (bitcoin fractions) every hour. Game consists of three mini-games where you can make random spins, the most likely is to earn some satoshis although there are also big prizes :)
FreeLitecoin works differently than FreeBitcoin, there is only one way to play where you can climb levels.
Level 1 -> 64 fields (4 give access to 2nd level)
Level 2 -> 8 fields (1 gives access to the 3rd level)
Level 3 -> 4 fields (1 biggest prize: 0.00100000 LTC)
FreeBitcoinCash works similarly to FreeLitecoin, but in this case the rewards earned are BitcoinCash (BCH)
