Block Puzzle Sudoku

I can tolerate the ads, and the actual play is decent. However, the games take a long time once the scores climb, and they can't be played out in one session. Most of the time the game will preserve the game status between sessions. HOWEVER, once in a while, for no reason, the game will reset, leaving the player with zero score. This has happened several times to me at around 15-20k points, so I am finally giving up and dumping it.

The game use to be so fun and now it's all ads. I do understand that's the way they make their money but they have so many ads popping up while you play it makes the game more frustrating than relaxing. After about three minutes of play here goes an ad then if you continue after two minutes an ad and it continues throughout the game so I took it off finally 😆

Fix the glitch please! I used to be able to turn pieces and make space for them when I ran out of space otherwise. Now it keeps saying I'm out of space even though my turns are on and available. I can see available moves I can do if I turn a piece, but it's saying I lose. Change it back please!
