Do not understand

Not good. I have no idea how to load a new game. I paid my one time fee for good Sudoku and do not know anything about how to initiate a game. Can I only play one a day? Can I play an advanced game? Nor do I know what the three vertical bars are for on the left side. No instruction set or definitions.
Hints? Do not want them. But no idea how to get them. Game is one time $4.99, but do not know if this means. NADA, NO INSTRUCTION. NO CLUES. NO CHOICES, NO GAME AFTER THE FIRST.

Gone Downhill

This used to be one of my favourite games but now it’s so irritating. I’m having to reinstall it constantly because of it hanging on opening. Please fix this!!!

BS “hints”

So far the app is great. 1-2 ads after each game is fair. What’s irritating is clicking on hint only to be shown a “naked pair” that I’ve already seen and eliminated the appropriate numbers for. Like, just say theres no hint to give.
