Launched in the 80’s, Tetris has rapidly become a game favorite by people of all ages. Decades later, Tetris still captivates. SideTris is a simple gadget that lets you play the game straight from the Windows sidebar.

The game is in GADGET format, which means it acts like a widget. You can move the window anywhere on the desktop simply by dragging it.

The software has two display sizes you can opt for. You can toggle between the small and large versions without losing any of the progress.

The frame includes a window that displays the next incoming block, the score, level and number of lines you’ve completed. Also, there are some controller buttons to help you move the blocks to the right and left, hasten the descent or turn the shape.

The keyboard arrows can also be used to play the game, while the space bar swaps between elements.

SideTris also comes with a few adjustable settings. For example, you can select the start level and a number of lines the game starts with. The game can be paused automatically when the mouse isn’t over the frame. Also, while the game is paused, the app can save the progress.

The game allows colored or black elements. You can customize the window appearance by choosing one of the available color schemes.

The bottom line is that SideTris is a gadget that can make you lose hours in front of your computer. The app is extremely easy to figure out, so inexperienced users shouldn’t have any problems with it.
