Can’t play Samurai anymore – Samurai Sudoku Review

I can’t play the Samurai Sudoku game on my iPad any more. An ad screen pops up and blocks the screen. The problem is I’m holding screen horizontally and ad runs vertically - so you can’t click or see the close “x”. This is my second review with no response. I used to play without a problem. Now I have to reboot and even that doesn’t always work.
