On this day in 1992, the first ever photo was uploaded at CERN. The image was of Les Horribles Cernettes, a do-wop band. It's a major cultural step as, up to this point the World Wide Web had been a tool purely for physics geeks, whereas after, well it was still a tool for physics geeks, but something had changed. The impact might not have been visible, but it was like the first flakes of snow setting off an avalanche. Without generosity of Tim Berners Lee giving away the World Wide Web for free, and people like Les Horribles Cernettes taking the first steps on the web, sites like this would never have happened, so this week's Sudoku Garden seems an appropriate time to say "thank you".

How to Play

Six plants fill each row
each column, each box of six
no bloom may repeat

Tap an empty cell
then choose your plant from below
watch the garden grow

Or pick a plant first
then tap the cells where it goes
faster hands plant more

Red borders will warn
when two alike share a line
rethink and replant

Ticked plants rest complete
all six placed in rightful soil
fewer choices left

The clock starts to run
the moment your first plant falls
how swift is your hand?

Every row, column & box needs all six plants
0:00

Select a plant, then tap cells

0/36 planted

Two ways to play: Tap an empty cell then pick a plant, or select a plant below then tap cells to place it.
