Remember that every puzzle could be solved logically (atleast I can guarantee that would be case with IPC).

Just few steps to approach H3:
1) r1c1,r2c1,r2c2 and r1c3 are shaded, r1c3 is unshaded. This also makes r1c4 shaded.
2) Now the "3" clue can be two ways -- (i) r3c1 r4c1 r5c1 or (ii) r3c2 r3c3 and r4c3.
3) There is letter 'B' already given, so from the list of choices only one word fits, which is "IB" , so 'I' at r1c5.
4) Immediately it follows, r2c4 r2c5 r2c6 will be shaded.
5) Now if the "3" clue follows (ii) , then there will be isolated blank cell at r2c3. (as there is no word or numeral of single size).
6) So now you get r3c2 r3c3 r4c3 r5c2 r5c3 as unshaded. So all these will contain some given characters/numerals.
7) It's easy now to fit three 4 digit numbers (as there is only one way).

Thanks Swaroop. Explanation really helped.

I have doubt regarding Hidden Pairs Puzzles. IB says as below
This Hidden Pairs puzzle will be based on one of the puzzle types that is elsewhere in the Puzzle Booklet. The type will also need to be deduced looking at the images.

My doubt is will only one puzzle type be used to match the hidden pairs or there will be multiple different puzzle types?

Only one puzzle type.

Thanks Deb!

Can anyone pls share more examples on Fillomino stars.

I have few questions regarding tomorrow's test.
1) Do I need to make any payment or is it free.
2) I start using Instant grading and at some point say after 2 puzzle submissions can I switch to the normal mode.
3) After I start the timer , I am logged out . Once I finish can I login again and submit the answers.

Pls let me know.

Thanks Amit for the puzzles.

Can someone pls clarify what is the general rule in a 3 point snake : Can the snake touch itself diagonally or not?

A. It is free to all.
B. Instant grading means once you submit the Answer for a puzzle you will instantly know whether your ans is correct or not. If on first attempt your ans is correct you will get full points else on seconds submission 90%, third submission 70%, fourth submission 40% of the points. After that it is nil points only.
C. Yes one can log out and again re-log in. But the timer will start from the first log in.

Three points are given. One is start of the snake, second end of the snake and the third one exactly the mid point of the snake.

The IB says the snake does not touch even at point mean it must not touch diagonally.

Can anyone who has practised share the solution for the 3-point snake puzzle provided by Amit.

Is there some technical issue - cannot see the "Start IPC 2015" button anywhere?

Dependency on flash etc ?

Did you see a login box?

It runs on flash, which you can get from https://get.adobe.com/flashplayer/

Nope ...cannot see a login box anywhere

Please install flash first - link in previous post. May be try from different browser.

Are you by any chance working on a mobile or some handheld device?
