Will do 
I second the mad clown. I don’t think there’s a point to having a paid and free version, not these days. I went down that route and it didn’t help.
It sounds like there’s a lot of variation in your game; Plenty there to offer for purchase and if there’s levels why not have some of them purchase only? As long as they don’t prevent completing the game, they can be purchased extras - perhaps playing them can make it easier to complete the game, but not prevent it.
Tiny Troopers had an excellent purchase system where you could buy extra lives if you die close to the end of a level or extra weapons etc. In that game, unless you’re really experienced, it’s sometimes easy to get killed regularly without a particular weapon etc. Makes real purchases with iAP much more enticing.
Hi Horace, thanks for your advice.
But there are I would say at least 70% of users that will not pay anything that is not realy required to play the game.
Maybe I should lock some levels and players as you say…
What reward ADS providers would you recommend (I am Basic license user for now)?
One question guys:
Is it allowed to give one time play of the level, and then lock the level after game over and require IAP via coins or directly or by other means?
No, not on iOS. You can’t do time limited or usage limited functionality.
So I can do create timer to go back to main level selector scene and to lock particular level?
Why not simply offer 3-4 levels for free. When they play out the last level, prompt a screen suggesting they purchase the full game.
Keep it simple.

Every level is somehow different. Maybe I should make a good promo video showing all levels.
Thanks Rob.
Even with different levels, the player should have an idea after three or four if they want to continue the game. That’s sort of the whole try-before-you-by mentality.
Or have an in-game economy where they buy consumable’s (more coins) that they can use to unlock more features.
And if you expect a lot of download and long play times, then Ads may be the best way to go.
