It's Google's nineteenth birthday -- and it is celebrating the occasion with a "greatest hits"-style Google Doodle that brings back some of its best and most iconic previous doodles.

The Californian search engine giant is famous for frequently updating its homepage with temporary "doodles" -- tweaks to its logo that mark events or honour significant people. This might just be an image, or it could be an intricate interactive game or toy.

Just click on the Google Doodle on Google's homepage and it'll launch the spinner. You might get Google Pacman, that has you play the iconic arcade game in a custom level based on Google's logo. Or there's an adorable minigame that has you help pangolins find love.

Snake is another option, as is one that requires you to reconstruct Beethoven's symphonies by ear.

Google Doodles only stick around for a day -- but after that, they're not gone forever. There's a complete archive of all old Google Doodles available to view and play with right here. Enjoy!
