Reached level 14 on your iPad but have to catch the train to work? Don’t panic – just carry on where you left off with your iPhone!
You know the drill – tap once for a wrong answer and twice for a true answer.
After a true answer has been found, the Auto X feature then fills in the rest of the wrong answers within a section to save your fingers!
Believe it or not, even the Professor makes a mistake from time to time.
But thanks to the multi-level undo feature you can go back as many turns as you need to get rid of those unwanted mistakes, fix them and move on.
It’s really annoying to spend ages on a puzzle and then discover you’ve filled in wrong answers.
If this annoys you, just use the Error Checker to see how you are progressing, but be careful – it costs you 30 seconds penalty each time!
Struggling with a difficult puzzle? Just use our special hints button.
No need to be stuck forever on a difficult level. Just use our hints button and we’ll give you a clue to get you going again – but beware, pressing it will cost you a 30 second penalty!
About the Game
The logic puzzle was first produced by Charles Lutwidge Dodgson, who is better known as Lewis Carroll, author of Alice in Wonderland.
In his book The Game of Logic he introduced a game to solve problems. Puzzles like this, where we are given a list of premises and asked what can be deduced from them, are known as syllogisms.
