Drop it, you've played enough.
Let's talk about addicting mobile phone puzzle games, shall we?
Scanning the list of upcoming games for the 1001 list a month or so ago, I came across Drop7, a title I'd never heard of before. Described by the writeup as a sort of mix of Tetris and Sudoku, but is neither, I was intrigued, and luckily for me, it was still freely available on the Play Store to download and give it a go.
Many hours later, phone batteries were dying through overuse, TV programs needed to be rewound to see what was missed, and even P2 is playing it far too often. I actually had to uninstall it from my phone to make sure I stopped playing it, only to download it for my Chromebook and, now, for the BlueStacks Android emulator on PC.
This is a staggeringly addictive game. Let's see what has got me hooked.
