Portal: Flash Version - puzzle platform 6.8Mb
This is another Portal game again partly based on the original Valve Portal game. It gets remarkably difficult very quickly, as you are limited by the game as to where you can place entry and exit portals (dark areas are automatically prohibited, but other walls/floors/ceiling may or may not permit portals. Use the mouse left click to set the first portal and left click somewhere else to set the second portal. Press the ‘R’ key to reset portals, as they often get placed other than where you want them! Portals in this game are bi-directional. There is a good (and often needed!) walkthrough at http://armorgames.com/walkthrough/107. You might end up cussing the screen bluer than a BSOD playing this one! It's a very enjoyable fun, but often very challenging game! Do try this one!
If it won’t play in your browser, use windows Media Player or the free Swiff Player (Google for this) - or you can play online HERE.
