. . . I've managed to find one anyway. It's an online game called 2048.
See? I just did it! I had to go to the site to get the link, didn't I, and then what happened? That was an hour ago! If that wasn't bad enough, I've downloaded it to my Apple devices. Now, I can avoid all kinds of work for hours at a time.
I found the link on the KenKen website, another terrific time waster. KenKen calls 2048, ". . . the Candy Crush for math geeks!"
How could I resist?
