How much play time should a puzzle app have?

JagonApps

Hi I am looking at making a puzzle type app with the easy levels lasting couple of minutes, and the harder ones 10-15 (perhaps 20) mins. But my idea can only have 15 levels because of the nature of it
Is this long enough?
What is the best playtime length for a puzzle game???
Would I be able to make it a payed app if graphics, ease of use etc. were top notch???

Many thanks

It depends on the puzzle hardness and amount of pieces. If you could show a video, the would be good. FYI - Not too many people often want to play 20 minute puzzles. But it's good to have some. People love time waisters. Maybe add a pause game and then you can save it for later.

"Is this long enough? "
… 15 good puzzles is long enough!
"What is the best playtime length for a puzzle game???"
…as long as it takes; so long as player is not bored
"Would I be able to make it a payed app if graphics, ease of use etc. were top notch???"
…certainly

what you want to try to do is give the player incentives to complete all the puzzles:
EX:
puzzle1 done … can play bonusPuzzle1
puzzles2,3,4 done … can play bonusPuzzle2
puzzles5,6,7 done … can play bonusPuzzle3
puzzles8,9,10 done … can play bonusPuzzle4
bonusPuzzles1,2,3,4 done … can play SuperBonusPuzzle (your longest and hardest one)
