There’s a mobile game I like playing called Ruzzle, I have the paid version and I’m aware that publishers find the paid versions less profitable than the free versions with ads, but still!
Last week Ruzzle started a permanent promotion to win coins which can be used in their weekly tournaments to increase your score. I took a look and discovered you have to play matches against a bot called “Wordbrain” who, quite frankly, doesn’t have a brain. Playing against it is so boring that you play for half the time and can then stop and still win by a healthy margin.
