Nurikabe - medium

This is a nurikabe.

Serendipity - easy

I like constructing puzzles that work inwards from the corners (specially nurikabe) and leave plenty of unclued space in the centre.

I dont know how the title justifies the rules of the puzzle ,but this is how it was called by the organizers of OAPC. I interpret this as a tetromino minesweeper with constrained tapa-like clues.

Rules: Place all the 7 tetrominos into the white squares without touching,not even diagonally.The clues indicate sizes of blocks of contiguous black cells around the cell with the clue.Figures cannot occupy the clues.

Recoverable Tapa - medium

I had introduced this variation in a test early this year,and it is appearing at the 20th WPC too,under the name Tapa restoration.

The nature of this puzzle allows you to use all single digit clues.

Rules: Exactly one digit has been removed from every tapa clue.Find the digits to Restore

the tapa.

Fillomino classic medium

This works out delightfully different.

Dotted Shikaku

Rules: Divide the grid into rectangles that do not overlap.Each rectangle contains exactly one number which equals the area of the rectangle.Unnumbered dots do not contribute to the calculation of areas.

Nurikabe - medium

Sum lines - medium

Fill the grid with numbers 1 through 8 such that clues outside the grid indicate the sums of groups numbers along each line segmen in that direction. The sums are given in the order they appear in the corresponding rows.Numbers cannot repeat in any row/col.

Fillomino :Garbage collector

This is a regular fillomino,except the polyominos cannot be rectangular.

Edited

Non-consecutive fillomino

This fillomino has an additional constraint where consecutive sized polyominos also cannot share an edge.

Edited: The broken bottom-left is fixed.

Deadomino

This is "one per row/column" fillomino renamed to a better(really?) sounding one.The new restriction on the classical version was (as he says with an element of doubt) introduced by anderson on his blog,the url of which looks like a substring of possibly one of the earliest(or even current)passwords of his email.
