Build a playable falling-block Tetris game on a canvas with a 10-column, 20-row visible board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Include all seven tetrominoes with legal spawn positions. Use Left/Right to move, Up to rotate clockwise, Down to soft-drop, and Space to hard-drop. Show the controls. - Reject moves and rotations that overlap occupied cells or leave the board. Wall kicks are optional; if unsupported, reject the blocked rotation without changing the piece. - Lock landed pieces, clear complete rows, move rows above downward, and spawn the next piece. Display score, cleared-line count, level, and a next-piece preview. - Award 100, 300, 500, or 800 points for clearing one, two, three, or four rows with one piece, multiplied by the current level. Start at level 1 and increase gravity speed every ten cleared lines. - If a new piece cannot spawn, show Game Over. Provide Pause/Resume and Restart, with restart resetting the board, score, level, and piece sequence state. Hold and ghost pieces are optional. Verify: Move and rotate the first piece, then hard-drop it. Check that it locks into the board, a new piece spawns, and the next-piece preview advances. Pause and resume, then use Restart and check the cleared board, score, and level.

Built playable Tetris in a single self-contained `index.html` (inline CSS/JS, no external resources). Game features: - 10×20 canvas board, all 7 tetrominoes (7-bag randomizer) with centered spawn, ghost piece, and hold (C) - Controls shown on screen: ←/→ move, ↑ rotate clockwise, ↓ soft-drop, Space hard-drop, C hold, P pause, R restart; touch buttons on small screens - Collision/rotation rejection (simple wall-kicks, rejects if all fail) - Locking, line clears, rows shifting down, next-piece preview, score/lines/level/pieces HUD - Scoring 100/300/500/800 × current level for 1–4 lines; level = ⌊lines/10⌋+1 with gravity interval `max(50, 1000·0.85^(level-1))` ms - Game-over when spawn is blocked, Pause/Resume and Restart (resets board, score, lines, level, bag/next/hold) Verified in browser: - Initial render: board, HUD, Next/Hold, controls, Ready overlay with Start; no console errors - Clicked Start → first piece spawned - ArrowLeft moved piece, ArrowUp rotated it, Space hard-dropped it → locked at bottom, score increased (hard-drop bonus), new piece spawned, Next preview advanced - Pause button → Paused overlay; Resume button → game resumed - Restart button → board cleared, score/lines/pieces reset to 0, level reset to 1, new piece/next preview Unverified: actual line-clear scoring/level-up and Game Over (not reached in brief play — code paths inspected), soft-drop timeout behavior, and long-term gravity at higher levels.
