I agree that it shouldn't be case sensitive, and it should clear the answer box with each new question. It would also be a lot more fun if you could pass (counting as wrong) just so you could see more questions - then the questions could be randomised, which would ultimately be harder since people wouldn't bother post the answers - but you would need more questions.
eichwulf - I don't think the question "Where is undefined?" was meant to be asked, and I went for the south pole but it appeared to be off the top left corner and gave me a score of NaN (or something like that) presumably because of some divide calculation involving such an enormous distance of wrong guessness.
I looked for the missing piece in the end but, after I'd moved everything back, I realised the car was upside down, and I definitely have no intention of spinning each piece 180 just to see what the pic looks like the right way up! I'm assuming that the reason I haven't got any recognition for completion (I was hoping to a switch to the pic without borders showing) is that it doesn't register as correct when upside down. Is that the case, or is there no end recognition>
I second Gchick - I had a piece missing, presumably under all the others but I couldn't be bothered to move every piece to look under it - alternatively if your intention was to avoid giving info about correctness of a piece, have a lock function which allows the user to click on a piece (solo or already locked to others) and another one they want to lock it to, so that the user could build up areas that they were sure about and could move as one unit.
Oh, and sometimes a ball pops a chain of another colour - not that I'm complaining about that. And shooting really fast pushes the lines back into their holes but tends to create the "shooting blues at yellow" problem.
A few bugs I've experienced are phantom balls left displaying from previous screens, being left with one yellow ball but only fire blues so can't complete the screen, groups of three or more not eliminating, particularly at the head of a line. I like the map and the short intense screens.
Nice, but I lost two pieces off the edge of the screen. I could see a few small black lines indicating where they were, but I couldn't select them with the mouse (maybe put a virtual edge just outside the real one to stop them going off screen, or make pieces selectable by tab with movement by cursor key to move them when they do).
Some of the answers are wrong:
A prime number is not a number with divisors of 1 and itself - as stated in the answer ONLY is crucial and not given as option.
1 4 8 9 - 4 is not prime so 8 is not the odd one out.
The question with the answer 20% does not accept 20 as a correct answer.
Other than that it was fine.
I really like the deck, it gives equal weight to number and symbol, and the colours make it easier to spot flushes. I have a question - it doesn't seem to recognise five of a kind, either as a kind or a full house. I don't know the poker rules, so is this as intended, or a bug?
