Feel free to pause the video and try to solve them before I show the answer.
After rewatching I’ve found easier way to solve some of the puzzles. I’ll share them below:
4:55 – You can see that the stars are blocking the second and last row, so the question mark has to be a star. So you don’t need to put out the triangle to solve it.
11:45 – After putting out the star in the second column you can see that the circles are blocking the first and last column on the row with the question mark, so the question mark has to be a circle. So you don’t need to do the whole crossing off rows and columns like I did.
Feel free to share your solutions if you find quicker ways to solve the problem and I’ll add them here 🙂
