Puzzles (69-74) IPC-2012 PRACTICE PUZZLES

Finally was able to find time and created few practice puzzles. I tried to make those puzzles which are not on my blog with few exceptions :p
Almost spent 1hr for creating Start Battle but was struggling at the end part. Will give another try later and if done then post it here by tomorrow. Besides below puzzles one can solve already existing puzzles on the blog which are as follows :-

Difficulty :- Between Easy - Medium
Puzzles   :-
Masyu
Draw a single closed loop using horizontal and vertical segments. It does not cross or overlap itself, and it may not visit all cells.The loop makes 90o turn at every cell with a black circle, but does not make a turn immediately before or after. The loop goes straight at every cell with a white circle, but makes a 90o turn immediately before or after or both. 

Snake

Locate a snake in the grid, whose head and tail are given. The snake does not touch itself even at a point. Numbers outside the grid indicate lengths of snake segments in the corresponding direction.

Graffiti

Paint some cells to create black walls. The numbers outside the grid indicate lengths of blackened cell blocks in the corresponding directions, in order. If there are more than one blacked blocks in a row or column,  here must be a white cell between the blocks. A snake travels through all the white cells, moving horizontally or vertically, without touching itself, even at a point. The head and tail of the snake is given.

Square Division

Divide the grid area into several square sub-areas. Each square must contain exactly one circle.

Square Division2 (Variant)

Divide the grid area into several square sub-areas. Each square of length N must contain exactly N circles.

Mastermind
Find out the correct series of symbols with the help of the information given by the black and white markers. Black markers indicate correct symbols in the right position, while the white ones mark correct symbols in the wrong place. Each symbol can occur only once in the solution.

Puzzles 66-67 (TRIO CUT) - PRACTICE PUZZLES FOR LMI TEST

Hey, As announced in earlier posts about LMI may puzzle test "NO NUMBERS". All puzzles were new to me. And getting familiar with that there is no other better way than creating a one. Although still other types i am trying to grasp it. I succeeded in making two of them for " TRIO CUT".
Rules : You can refer the Instruction Booklet (Download) - Sample puzzle given along with rules.
I am giving rules here again so that no need to go to IB all the time.
1) Paint some cells black to make some triminos so that each trimino will be cut twice by thick lines.
2) Each region bordered by thick lines should have three painted cells.
Difficulty :- Between Easy and Medium ( As first time for me too). Will see if i could get a hard one.

Puzzle No 65 - LITS

Thanks to    Δόλιχος to point out this issue with the 1st version. It's fixed now.
So This is my first Puzzle after the break. So had to be something different. It's again a new type on the blog. Also, I made of a large size 15*15. Moving towards the Puzzle.
Description :
It is LITS puzzle. Click on the name for the rules. I thought of using only L,I,T,S and make it although reflected rotated and of irregular size. As you will see in the left side of the puzzle most of them are L or I or T or S. But didn't succeed in that. Obviously this also fine with me as it is the first one for me. Njoy !!
Difficulty :- Hard
