How to use 俄罗斯方块
Arrange seven original tetromino shapes on a 10×20 board with keyboard and touch controls, ghost landing guidance, next preview, scoring, levels, pause, mute, and restart. Start with the button or any movement key. Use ArrowLeft/ArrowRight to move, ArrowUp to rotate clockwise, Z to rotate back, ArrowDown to soft drop, and Space to hard drop. Touch buttons provide the same actions. The active result always remains visible in the workspace, and any provided Reset or New game control restores a documented starting state instead of quietly preserving an old outcome.
Mouse, touch, and keyboard-friendly controls are provided wherever the underlying action can be expressed without a complex gesture. Status changes are written as text as well as color or motion, so the next step is not hidden inside the visual board.
Rules and method
The original local engine uses a 10×20 integer grid, seven-bag distribution for the seven standard tetromino kinds, a next preview, a ghost landing guide, bounded wall kicks, and one stable requestAnimationFrame gravity loop. A single, double, triple, or four-line clear scores 100, 300, 500, or 800 points times the current level; every ten lines raises the level and shortens the drop interval. The game runs in the current browser tab, so ordinary play does not require a remote opponent, game account, or cloud session.
The page names its actual rule set instead of implying that every regional, tournament, classroom, or commercial version behaves identically. Visible counters, board state, selected controls, and completion messages make the result inspectable rather than treating animation as proof that an action succeeded.
Practical play and accessibility
Keep the stack low and level, avoid covered holes, and read the next piece before committing to a narrow column. Soft drops add one point per cell; hard drops add two points per cell, so use them when the landing is clear. Restarting is useful when learning, and a lower difficulty or slower pace is a legitimate control choice rather than a lesser result.
Interactive targets use native buttons or labelled controls where possible. Drag, swipe, sound, timing, and motion never stand alone when a simpler control can perform the same job. The layout reflows for a narrow screen, visible focus remains available, and the site-wide reduced-motion preference limits decorative animation.
Privacy and limits
This is an original browser puzzle with generic tetromino names and local session state. It does not copy a protected logo, board skin, music, brand wording, trade dress, leaderboard, or claim of affiliation with a commercial block game. These boundaries keep a casual entertainment page from making a medical, legal, financial, diagnostic, spiritual, or performance claim it cannot support.
Names, choices, moves, scores, drawings, and settings are processed locally and are not submitted to NexaCurrent by the tool. Reloading or closing the page normally clears the current session. No login, cloud save, leaderboard, advertising profile, or remote opponent is involved in ordinary play. If a result affects another person, a prize, safety, money, consent, or access, use an appropriate transparent process rather than treating a browser game as authority.
