### 5/5 — Enjoying this game!

*2018-01-25*

My husband got me started on this game, and I love it. It's addictive! LOL I was having a difficult time until my husband showed me where to get a tutorial at the bottom of the screen with an English gentlemen who shows you how to solve the puzzle with rather easy steps! I'm still on the easy puzzles, but who cares! When I get bored, I'll move up to the next level. This really helps my brain to stay active, too since I am now older!! 😉
