Country : India | In true or lie sudoku, r6c5, r7c4 must be 9 because of 8 at r8c5. Then r2c6 must be 9. r1c8 must be 8 because of 9 at r8c8. Then r2c9 must be 7 and r3c8 must be 5. Then I am not finding a place for 5 in box 6.
Where I went wrong. |

Where I went wrong. The clue at R2C9 should be 7. Fixed the IB. |

Country : India | Question in email about Triomino Sudoku
All shapes need to be used?
No restriction on number of triminoes?
Triminoes can touch diagonally?

As per rules if 9 is next to arrow cell with arrow pointing towards 9 then arrow cell will contain 1. If arrow cell is 2 cells apart from 9 in the direction of arrow then it will contain 2 and so on.
Below link contains the solution of the one of Search 9 Sudoku which will help you understand the rules clearly.

Not that I know of. Why not just print out the many that are on this and other sites? It'll help you more to solve on paper anyway since most Championships have only on-paper solving.
Edit: Just remembered Rishi released an app recently. I'll allow him to post details. |

Though I have given the link to the app for android, my personal suggestion is to practice on paper rather than on mobile devices. During ISC you will be mostly solving on paper and better to be prepared for that.

Look at the clues on the left side. Since they are in pairs, the first digit in C1 has to be one amongst the clues. Hence look at digits that occur only once in the clues and you can safely assume that digit will be the first digit visible in its corresponding row. You can proceed from there : )

For Triomino, begin solving for the digits 1 to 6 like a classic sudoku. Once you can proceed no further then look how the black cells play a role and you will be able to proceed.
For Deficit-Surplus, ignore the shapes to begin with and concentrate only rows and columns. Since all digits from 1 to 8 have to be in any given row or column, that would be the best start.
