You may have seen them advertised; some of the ads specifically say that they don’t do things that other such apps do to make money (like in-app ads, requiring friend recommendations, cash-in limits, or “top ups,” whatever those are). I’m assuming that spending money isn’t required, or it’d be straight up gambling.
So what’s left? What’s the catch? I don’t particularly want to give them search engine hits, because whatever the business model is, I’m sure it’s at least a little scummy.
My guess (not having played any of these games) is that, while spending money isn’t required, it’s an option. (And I could see getting stuck some number of levels in, and seeing that getting a hint would only cost $1.99, so you go for it.)
In the Apple App Store, there is a field for whether “in-app purchases” are possible. Do you see that if you look up the game in the app store?
Depends on the game. I’ve seen quite a few mobile games that were out and out scams, so false advertising.
More common was the competitive games that were absolutely pay-to-win. You didn’t have to spend money in them, true, but you’d loose against anyone who did spend that money.
Third was money = time. More true for base/farm building types. You didn’t have to spend money at all, but you’d often do everything you wanted, to be told that the next action wasn’t available for 4 / 8 / 12 + hours. Or you could spend a teeeeensy bit of money and it would happen immediately.
Fallout Shelter had a good bit of it, plus options for series characters, bonus loot, etc. Nothing you HAD to have, but it made life a lot easier.
I just wasn’t sure if depending on whales was economically viable for an app that actually has cash payouts. I’ve heard that whales outspend FTP enough for games, but I imagine that money games would be different; you can actually keep direct track of losses, and you have nothing to show for it, not even a cool powerful unit or a top world ranking.
Note that there is a Wikipedia article on free-to-play video games, as opposed to premium games (in which you have to pay to play at all) or freeware games.
I had a game featuring a panda. I assumed it made money off the ads. I got bored of it before I was able to make any real money, so the whole thing could have been a scam
