Fit all the beach-themed words into the right space in the blank grid and develop some computational / logical thinking skills that computer scientists use, while also finding out about safety on the water with this puzzle from Computer Science For Fun, an outreach project from the Computer Science department at Queen Mary University of London.

The pack contains four PDF files
• 00 CS4FN at the beach - information
• 01 CS4FN at the beach - A4 UK water safety kriss kross colour.pdf
• 02 CS4FN at the beach - A4 UK water safety kriss kross puzzle black and white.pdf
• 03 CS4FN at the beach - A4 UK water safety solution.pdf

The information sheet has instructions, links to a slide deck and more detailed instructions, links to more examples of kriss kross puzzles and other puzzles and also a set of the same puzzle for US printers.

Briefly, while any of the 5-letter words could fit in any 5-letter space in the grid you need to take account of the other words that can fit around them. Every word will cross over with at least one other word, both sharing the same letter - so puzzlers need to consider the numbers of letters and the position of those letters in other words to find a match. If there looks like there could be more than one match then you may need to come back to that word. If there are four words with the same number of letters and you think you’ve placed the first three correctly then you can be reasonably sure that the final word can go straight into the remaining space, without thinking about the words crossing it - as that’s the only place it can go.

This puzzle is based around the phrase “Float To Live” (11 letters without spaces) which is a campaign from the Royal National Lifeboat Institution.
