The UKPA Sudoku and Puzzle tournaments took place last weekend - you can find all the puzzles here. I've solved all the puzzles, they're pretty good!

This Tapa (Trimino) is a variant featured in Prasanna's round (Round 2). It's another neat twist on the classic Tapa genre. I'm sure Pras would want to plug https://www.gmpuzzles.com/blog/2014/01/tapa-triomino-prasanna-seshadri/ as well, so I'll do it for him.

Rules: Shade some cells so that all shaded cells form one orthogonally connected area and no 2x2 region is entirely shaded. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. The shaded cells must also be able to be divided into L triminoes. (An L trimino is a 3-cell shape that looks like an L).

Solving Note: The puzzle is set to yajilin mode - this will allow you to shade cells, mark unshaded cells, and draw lines to indicate L triminoes. Note that the division into L triminoes need not be marked for answer check, but will probably be helpful during solving.
