Memorable Pairs
This is an online version of the world-famous memory game, where players have to find pairs of fitting cards.

Game Instructions
A deck of 30 cards lays face down on screen. Choose two cards and click on them to turn faces up. If both are showing the same pictures, then you have found a pair and they will stay open, otherwise both cards turn back. Find all 15 pairs in as few steps as possible.

Each attempt of flipping two carts counts as one step. If more than one player achieve the same score, the faster ones are ranked better. The clock starts when flipping the very first card.

Game history

Today it is known under various names like Concentration, Memory (trademarked by Ravensburger in German), Shinkei-suijaku, Pelmanism, Pexeso or Pairs.
The photograph on the back of the cards was taken in a thunder storm near Graz (Austria) in May 2003.
