Google turns 25! Tech giant celebrates its birthday with hidden surprises, Easter eggs and its iconic spinner

In September 1998, Google was created in a garage by two Stanford University students – a humble beginning to say the least. Who would have thought a quarter of century later it would be the world's most used search engine with unprecedented access to our personal data? To mark its 25 birthday, Google has packed its site with Easter Eggs, including a new Google Doodle – a temporary alteration of its logo – with '25' in place of where the two Os would normally be. Meanwhile, if you enter'Google 25th birthday' into the search bar, colourful confetti will rain down over your results. The tech giant has also brought back its'birthday surprise spinner', which lets you play interactive games from its archives, including Pac-man, Snake and Tic-tac-toe.
