Block Drop is a Tetris like falling block game: move and rotate seven shapes to fill complete rows. Play solo Classic, send garbage lines in Battle, race to clear 40 lines or work together in Co-op. Two players can share one PC keyboard; on desktop or phone, six AI levels can be your opponent or teammate. Play Block Drop free in your browser against adjustable AI. No download or account.
Why play Block Drop here?
Share one PC keyboard for a two-player battle, a race or a co-op challenge. Playing alone? Choose from six AI levels, from a hesitant novice to a stronger planner who sets up multi-line clears. Battle turns clears into garbage attacks; Race lets both players chase 40 lines without attacking each other. In Co-op, clear 40 lines together within three minutes: your clears automatically help remove a partner's garbage and shorten their wait to return after a top-out. Solo Classic levels up every 10 cleared lines, speeds up and saves your best score. On a phone, choose Classic or an AI match and switch between two button layouts and gestures. Your current game and Classic record stay in this browser.
How You WinIn battle, outlast the other player. In a race, be first to clear forty lines. In co-op, clear forty lines together within three minutes. In Classic, level up every ten cleared lines and chase your best score.

How to play Block Drop in one minute
Choose Classic to play alone, or pick Battle, Race or Co-op and choose an AI or a friend sharing your PC keyboard.
Click, tap or press a game key to start. In Classic and AI matches, arrows move, Up rotates, Space hard-drops and C holds a piece for later.
Use the outlined landing guide to place pieces. Fill all ten cells in a horizontal row to clear it; keep the stack below the top.
Follow your mode’s goal: outlast the opponent in Battle, clear 40 lines first in Race, clear 40 together in Co-op, or build your best score in Classic.
For local two-player games, P1 uses A/D to move, S to soft-drop, W/Q to rotate, Left Shift to hard-drop and E to Hold. P2 uses Left/Right, Down, Up/Right Ctrl, Enter and Right Shift. Phones support Classic and AI matches; use the center switch for Classic buttons, Modern buttons or Gestures.
Playing Block Drop here: common questions
Is Block Drop free, and do I need to download anything?
Block Drop is a free Tetris like game that runs in your browser. Open it on a computer or phone; no download or account is needed.
Can two players share one PC, or play over the internet?
Two players can share a keyboard on one PC for Battle, Race or Co-op. Use a wide window so both boards fit. There are no network rooms or remote matches; friends on separate devices cannot join each other.
Can I battle against AI or have an AI teammate?
Yes. Choose one of six AI levels for an opponent in Battle or Race, or a teammate in Co-op. Lower levels think more slowly and sometimes make weaker choices; higher levels plan further ahead and set up multi-line clears. All levels take time to observe and execute their moves.
How does Battle mode work?
Play a best-of-three match against AI or a friend on the same PC. Multi-line clears, T-spins and combos can generate garbage attacks. An attack first cancels your incoming garbage, then any remaining attack can be sent to the opponent. Win a round by outlasting the other player.
How do Race and Co-op differ?
Race sends no attacks: be the first to clear 40 lines. Co-op gives you a shared goal of 40 lines within three minutes while garbage waves arrive. Every four personal clears charge an automatic assist that removes up to two of a living teammate’s garbage rows, leaving their normal rows intact. If a teammate tops out, keep clearing to shorten their revival wait; if both players are down together, the game ends.
How do Classic levels and high scores work?
Every 10 cleared lines advance a level without resetting the board. Speed caps at level 15; levels and scoring continue until top-out, with no return to the starting speed. Your Classic best score stays in this browser across refreshes and new games.
Can I play on my phone with buttons or gestures?
Phones support solo Classic and AI matches. The center switch cycles Classic buttons, Modern buttons and Gestures. Drag sideways to move, tap the left or right half to rotate, swipe up to Hold, hold and drag down to soft-drop, or flick down quickly to hard-drop. Same-screen two-player play needs a PC keyboard and a wide window.
Is my game saved if I leave or refresh?
The current game saves automatically in this browser, including the boards and held pieces. Returning restores it paused, ready to resume with a click, tap or game key. Current games and Classic records do not sync between devices; clearing browser data removes them.
Complete Rules
Classic starts at level 1 and advances every 10 actual cleared rows, carrying excess rows forward. The board stays in place. Level 15 reaches the speed cap of 20 rows per second; levels and scoring continue without a time limit or a return to slow speed. A top-out ends the run.
Classic scores ordinary one/two/three/four-line clears at 100/300/500/800 × level. Full T-spins clearing zero/one/two/three rows score 400/800/1200/1600; Mini zero/one score 100/200. Back-to-back four-line or full T-spin clears multiply base points by 1.5; consecutive clears add 50 × combo index from the second clear, and a perfect clear adds 2000. All use the level before the clear. Soft drop adds 1 per row and hard drop 2, without a level multiplier.
Your Classic best updates during play and stays in this browser across refreshes and new games. Results show score, level, total rows and a new-best announcement when applicable. Records do not sync between devices; clearing browser data removes them.
Pieces use a seven-bag randomizer: each bag contains one of every shape. Battle and race give both players the same stream; co-op uses independent streams. Five upcoming pieces are visible, and the AI sees only this public information.
Two-player modes use one row per second; Classic accelerates with each level. Grounded pieces have a 500 ms lock delay, reset at most 15 times by movement or rotation. Hard drop locks immediately; the fast trail is presentation only.
Battle is best of three. Ordinary one/two/three/four-line clears produce 0/1/2/4 attack rows. Full T-spin singles/doubles/triples produce 2/4/6. A perfect clear produces 10 instead of other attack bonuses. Consecutive clears build combo bonuses; consecutive four-line or full T-spin clears add one back-to-back row.
Attacks first cancel your ordinary pending garbage, including packets still travelling. AI matches use full outgoing attack; same-screen PC battles offer 100%, 75% or 50% under Handicap, retaining fractional units. Simultaneous outgoing attacks cancel each other. Garbage becomes eligible after one second and rises on a lock, at most eight rows per lock. Clearing does not indefinitely defer the remainder.
After three minutes of battle, both players receive one uncancellable pressure row every ten seconds. Six minutes ends an undecided battle in a draw. Racing sends no attacks; both players aim for 40 lines, with a six-minute limit.
Co-op starts with two garbage rows per player. Every 25 seconds a two-row wave alternates between players; at most two garbage rows rise on each lock. Every generated row changes its hole column, including across waves, avoiding a straight four-line well. Clear 40 combined lines in three minutes, but simultaneous top-outs take precedence and lose the game.
Four personal clears charge an automatic assist. If the partner is alive and has garbage, it removes up to two tagged garbage rows at their next lock. Ordinary stacked rows only move down and remain intact. Charge is kept when there is no garbage; no assist button is needed. A downed partner cannot receive cleanup; clear lines to hasten revival instead. Returning players have three seconds of wave protection.
Your First Game
Click, tap or press a game key to start after a brief 0.8-second preparation. Resuming a paused game uses a 0.6-second fade. Both players and the AI stay still during these transitions; the starting input does not move or drop a piece. Pausing, leaving the tab and restoring a saved game do not advance the game clock.
With AI or in Classic, use arrows to move, ↑ to rotate clockwise, Z counterclockwise, Space to hard drop and C to Hold. P1 can also use A/D/S, W/Q, Left Shift and E.
Local P2 uses arrows to move, ↑ clockwise, Right Ctrl counterclockwise, Enter to drop, Right Shift to Hold. Esc pauses. Open Keyboard controls in the sidebar for the complete bindings.
The center switch cycles Classic, Modern and Gestures without restarting. Classic: move left/right, rotate above, soft-drop below; Hold at lower left and Hard Drop at upper right in the right-hand group. Modern: movement and drops on the left, both rotations and Hold on the right. Hold direction buttons to repeat. Pause is also in the center.
Gestures: swipe or drag sideways to move, reversing without lifting; tap the left/right half of the board to rotate counterclockwise/clockwise. Swipe up to hold. Hold then drag down to soft-drop, releasing to stop; flick down quickly to hard-drop. Only the layout switch and Pause remain below the board. Releasing a sideways drag never rotates or holds, and soft drop never upgrades to hard drop. The first touch only starts or resumes play; it does not move or drop a piece.
Practical Strategy
Keep the stack fairly flat and avoid covering empty cells. A buried hole is usually harder to repair than a missed small clear; not every piece needs to build a four-line clear.
Leaving a vertical well can prepare a four-line clear, but lower the stack when the top approaches. Higher AI levels actively build these plans; lower levels can rely on ordinary clears.
Consider Hold and previews together. Hold does not create an extra piece or remove holes. After using it, lock the current piece before swapping again.
In co-op, watch the partner’s incoming rows and stack height. Prepare a clear as danger rises; after a top-out, your clears shorten revival. Automatic cleanup assists help a live partner with garbage rows.
Winning and Special Rules
A T-spin is more than rotating after touching down. The last successful action before locking must be rotation, at least three of the four corners around the T centre must be occupied, and facing corners or the kick classify it as full or Mini. Rotating into a shaped cavity can complete three rows at once.
Mini spins have no base attack here; a two-line Mini upgrades to full. A hard drop that travels down clears the spin marker; locking without vertical travel preserves it.
The six levels are Novice, Beginner, Casual, Skilled, Advanced and Challenge. Novice sometimes chooses a weaker near-best candidate, rather than always choosing badly. All levels retain observation and input delays. Difficulty changes immediately without replacing the current board.
The browser saves at placement, Hold, assist and periodic time checkpoints, and restores paused. A new game uses a new seed and archives the previous session. Rich effects are always used. Choose from four materials and toggle audio in Appearance & sound.
Common Mistakes
A single clear normally has no base attack, but combo bonuses can still create an attack. Generated attack differs from delivered attack because cancellation and multipliers apply in between.
Same-screen two-player play needs a wide PC window and keyboard. There are no network rooms or remote matches. Phones support AI and Classic.
Garbage-rise animations, clear effects and drop trails do not stop the rules clock. An animation still playing does not mean the piece remains unlocked.
Block Drop FAQ
When do clears attack the other player?
Only battle sends attacks. Ordinary clears of one, two, three or four rows produce zero, one, two or four attack rows. T-spins, combos and back-to-back difficult clears can add more. Cancel your incoming garbage first, apply the outgoing multiplier, then cancel simultaneous crossed attacks.
Can I use Hold on every piece?
Hold can be used once between spawning and locking a piece. An empty Hold slot takes the next piece; otherwise it swaps the two. The outlined ghost shows where a direct drop will land.
Can a downed partner return?
Only co-op offers revival. The default wait is 12 seconds; each partner line saves two seconds, with a minimum of three seconds after falling. If both players are down together, the game ends immediately.
