Although, if I had to think of beginner tips - knowing the keyboard shortcuts help a ton in getting familar with the game and one can use the "enter" key until you get use to it
I personally learnt by using the starting scenario of the shelter to get familiar with getting the basics of water purification, food sustainability and crafting going and camped out in the shelter and get my crafting up to scratch.
I know that I started to enjoy taking advantage of the weaker zombies in the early game and try and find a small town and try clear it out for a nice cushion to get one up to have a lot of raw material on hand, but that is more when one is more confident in the ability to handle zombies and found a style of play one enjoys
I know older titles are usually the topic in this community but a lot of the popular f2p games are getting pretty old now too, and if you're like me you've been curious about some of them and even pleasantly surprised now and again....
If you mean free-to-play in the sense of a commercial game that one can play without payment, but where it is supported by data-mining or in-app-purchases or ads, I can only off-the-cuff recall playing a few games in that category:
World of Warships. I played one round against humans.
Defense of the Ancients 2. I played one round against human players and some time against the computer.
Fallout Shelter. I didn't like it much, though I do like the mainline Fallout series.
I remember some gamebook game on Android that showed ads at the bottom.
I'm not playing any of those currently. Broadly-speaking, I don't like the model. I'd rather just pay up front.
If you're talking about free-to-play-with-the-aim-of-selling-you-on-a-larger-game, I've played plenty of those -- in the 1990s, shareware and demos were a common way to promote a game. But they've kind of fallen out of favor in terms of DLC. I don't think I've played any of those for a while.
If you're talking about entirely free games, then I've played plenty of those. I think the two that I'm currently playing off-and-on, both open-source, would be:
Shattered Pixel Dungeon, an Android roguelike. !pixeldungeon
Cataclysm: Dark Days Ahead, a (mostly PC; there's an Android build and you can play it on a touchscreen, but it's really better-suited to a keyboard) open-world roguelike. There's a not-very-active Threadiverse community at !cataclysmdda; the subreddit is much more active.
any tips for playing CDDA
