Amazing quiz, I really like the idea, it's very creative! The rules were a little complicated, but I managed to get all of them. If Egypt, Taiwan, and Burma have to be included, maybe you could fill them in without requiring to try random tiles to get them?

Thanks for the feedback! True, it would be more sudoku-like to have a few pre-filled answers; but I eventually decided against it, as there were so few answers in the quiz overall – and because I rather like the undisturbed colour pattern at the start :D

Maybe you could pre-fill one of these countries, preferably Taiwan. Just to give us a simple idea of what the quiz is like. I also really like this idea! (My own quizzes are pretty cool . . .)

Nice quiz, was a little confused which quadrant had countries with 4, 5, 6, and 7 letters as I interpreted it to mean the top left would be the 4 letter countries and not the bottom left.

Yeah, if you are looking at it on a phone you don’t see the key unless you scroll across but actually you have enough time to work it out so to make it a little more challenging you could omit the key altogether. Great quiz thanks.

i think you could honestly do with less time - i was able to brute force where egypt taiwan and burma go just from trying them all, and then the rest is markedly easier, so perhaps lower the time allowance to stop people doing this. really creative idea though, amazing work! nominated

The point is you don’t guess and check. You can, but the idea is there is only one place each country can go, and the rules let you know where.

good quiz! Would be a little nice to not have to guess which 1 country was put in the quiz with multiple countries in a particular continent that have a certain letter length as well. (Angola, Zambia, Gambia, Guinea, Uganda, Rwanda, Malawi, etc.; Nigeria, Senegal, Algeria, Eritrea, Somalia, Namibia, Morocco, Lesotho, etc. goes for a while), maybe just fill in a box where just one of these is typed? I'm glad we at least got 3 of the countries to know to put in there

You don't need to do that guessing. The rows and columns are alphabetical. So once you get to the African country with six letters, you know it comes after Tu (because Tuvalu is filled in above it). So it's either Uganda or Zambia. It can't be Zambia, because there's only one country alphabetically after Zambia (Zimbabwe), and you need at least two countries below that square to complete the yellow section. So Uganda is the only country that fits. Once you figure out where Burma, Taiwan, and Egypt go, you can do the rest with very little guessing (maybe even with no guessing, but I definitely took some guesses).

It's basically their way of giving you a few answers at the start (like regular Sudoku) so the quiz isn't ambiguous. When done properly after getting these 3 in, you don't have to guess any answers.

It’s clear that a lot of people just try countries and especially the three given ones, since they are the top three answers. I feel sorry for those people because it’s a lot more fun to only enter an answer when you’re absolutely sure. I only got taiwan as the second to last answer on my solving path. Although I remembered a bit late that it was given, so I might have gotten it sooner otherwise, but definitely not as the third answer.

For the quizmaster, you might consider adding a fifth rule that guessing isn’t necessary.
