In steem monster, initially you invest 10 usd for the pack of basic cards, after that you can:
a) buy packs of cards (2usd), there are cards valued from 0.10 to 300 usd, are 5 random, common, rare, epic, legendary and gold version of the cards which are more expensive.
b) you can go to ask for rented cards, with 40 usd, good set, that will allow you:
1. Make quests, fight and win 5 times with an element and you get cards according to the ranking you have, diamond are like 8 or 12 cards, there you can touch valuable cards of 200 usd or more.
2. Play tournaments, there are tournaments of 15, 50, 100, and up to 500.
3) Play and rank, as you rank you win a token that is exchanged for steem, in the engine steem exchange, depending on the ranking you are in, the type of cards you use (the gold are the most dec produce) if you win an opponent with more ranking point than you, you produce a number of decs.
4) when you rank, go up and there are seasons, they last 15 days, there they give you a certain amount of cards, again you can get valuable cards.
c) There is a market that works like this:
business model:
1 You can buy accounts, and have delegated cards (i.e. you have an account where you accumulate the cards, and this is going to lend it to another of your accounts), you lend your cards to another of your accounts to rent it, usually the deals are 50% and 50%, you agree with a person who wants or do quest, or play tournaments or both, in addition to quest cards, and end of season, that's how you have income.
Why does this model work? Because the game is absurdly profitable, you delegate cards, the account that has them, can only use them, can't sell or send, so you can't be scammed.
b) Simply rent cards in steempeak, a page that offers that service so you can rent your cards or ask for rent.
How does this model work?
People load steem/sbd to the page (it's to their account inside the page), there you can determine or set how much is the fee, the time of card rental.
That way you get income with your cards.
d) Buy or sell cards, you can go to steempeak and leave bids, there are always users who sell at that price obviously lower than the market value. You can burn the cards and get DEC.
It also has a 5% lifetime reference system for card pack purchases.
The secret to generate income in this game is through at least 10 accounts, the earnings range between 200 and 900 usd.
This is the case with steem Monster.
Now I will explain how Gods Unchained works, it has even more players, people who invest a lot more, there you only win if the cards you get in the pack turns out to be good, another way to win there is through the ranked, Friday Saturday and Sunday, win a certain amount of battles, and achieve a ranking, the best or those who reach a certain ranking give them exclusive cards and clear diamond cards that are worth 1 eth or more, and are sold. Sometimes they activate the raffles, in those moments they give tokens every time you win the fights, you sell the token, you can make trading in the market, accumulate tokens and use it for the raffles, the cards that raffle are absurdly expensive, that encourages the market to be constantly buying.
Kingdom Beyond, works buying chest, selling heroes, playing and accumulating gold that is exchanged for items, there is an item that can leave, recently bought 15 of those for 1.25 eth, it should be noted that they do fighting against monsters to get the gold and then the item, there are those who make money in the market buying and selling, you can raise heroes and then sell them and so on, but the most lucrative way is buying chest, you can get expensive items.
You could explain another business model and how it works, in which game.
