Cosmos Gems is a puzzle game on www.flash-games.net in which you can earn your score by moving various gems. The left part in the game records the level you are playing and the changing scores when you are playing. Destroy gems by creating lines of 3 or more gems of the same kind and get a high score. You can move the gems by using the mouse to click and swap adjacent gems. There will be a number of differently-shaped diamonds appearing in the game, such as pink triangle, yellow square, yellow star, blue dew, green pentagon, and so on. A red progress bar on the top stands for time limit. When it runs out, you will lose the game. When you get through level 1, you can play the next level and go on to others. When you failed, you can enter your name and press submit button to send your score. Get your rank.
If you want to play this game offline and without any browsers after December 2020, then download .swf game file and use any Flash Player that runs .swf files.
For Windows users, I recommend ARFlashPlayer (it supports fullscreen option) or official Adobe Flash Player. Both programs are portable.
Another way to play flash games is to install SuperNova SWF Extension (it works in Chrome only).
