What Is ROTETRA?
ROTETRA is a tetromino stacking puzzle by Michael Kamm, published on itch.io under the name sharkwithlasers. You move and rotate falling pieces, but you can also turn the entire board and juggle several pieces at once. The separate grid controls change how you approach the familiar task of fitting block shapes together. The creator lists the project as in development and provides an HTML5 browser demo.
This page opens that hosted demo when you press Play Now. Its title screen identifies it as a demo, so treat it as a way to try the central idea rather than a promise of every feature planned for the full game. The creator’s page links a separate desktop demo on Steam and describes a larger collection of modes for the complete release.
How to Play ROTETRA Online
Select Play Now, allow the browser build to finish loading, and click inside the game so it receives keyboard input. Follow the title prompt to reach the menu, then select play. The surrounding webpage’s Play Now button opens the player; the game’s own menu starts your session. Use the fullscreen button if you want more space to watch the board.
Begin with the distinction between rotating a piece and rotating the grid. Z or the up arrow changes a piece’s orientation. A and D turn the whole board. Try these actions separately while learning the controls, then combine them as you become familiar with the layout. Watching both the blocks and the board orientation helps you keep track of what each input changes.
Movement, Drops, Hold, and Pause
The left and right arrows move a piece. Down arrow performs a soft drop, while Space performs a hard drop. C is the hold command. These are the defaults published by the creator; if you have changed your bindings in options, use your own settings. Keeping the movement, rotation, drop, and hold commands in mind gives you a practical checklist before attempting a faster session.
Esc and Enter are the documented pause keys, and the creator explicitly marks pause as not rebindable. Other keyboard controls can be rebound. If a key appears to affect the webpage instead of the game, click inside the player again before continuing. The game runs inside an embedded frame, so keyboard focus matters when switching between the instructions and the puzzle.
Gamepad Controls
The creator also publishes rebindable gamepad controls. D-pad left and right move the piece. The south or east face button rotates it, D-pad down soft drops, and D-pad up hard drops. Either shoulder button holds a piece. The left and right triggers rotate the grid, and the west or north face button provides an additional grid-rotation input.
Start pauses the game and, like the keyboard pause command, is listed as not rebindable. Button positions are used here because controller labels differ between devices. Keyboard and gamepad instructions are available from the source, but touchscreen controls are not confirmed. Use a computer with a keyboard for the documented browser setup; a responsive webpage alone does not establish phone gameplay support.
Browser Demo and Planned Full-Game Modes
The official listing says the full game will feature at least eight modes. Its named examples are Standard, Cross, Classico, and Puzzle. Standard is described as evolving from one piece to four. Cross starts with four pieces at once. Classico uses opposing pieces on an overlapping grid, while Puzzle is described as a collection of handcrafted challenges exploring the mechanics.
Those descriptions belong to the creator’s full-game plans. They are not a checklist of modes guaranteed to be unlocked in this browser demo. Check the menu of the build you are playing for its available choices, and follow the official page or linked Steam listing for current release information. No full-game purchase is required to open the free browser demo shown here.
