Forge Drop

Forge Drop is a Tetris-style falling-block game on a standard 10x20 grid. Seven piece shapes fall in randomized 7-bag order. Every set of seven contains each shape exactly once before the bag resets. That removes the long dry spells for any single piece type that older random generators had. A ghost piece at 20% opacity shows where the current piece lands. A 500ms lock delay, reset on any move or rotation, gives you time to adjust after a piece touches the stack.

Scoring follows the classic line-clear system times your level. A single line clears for 100 points, a double for 300, a triple for 500, and a four-line Tetris for 800, all times the current level. Soft-dropping adds 1 point per row. Hard-dropping with the spacebar adds 2 per row and locks the piece right away with no delay. Level goes up every 10 lines. Speed follows a curve from 800ms at Level 1 down to 30ms at Level 20 and beyond.

The rotation system uses SRS-compatible wall kicks. Five offset tests per rotation state for standard pieces, a separate set for the I-piece. Pieces can spin into gaps that look too tight. Delayed Auto Shift handles held-key movement with a 170ms initial delay and 50ms repeat. That keeps fast sliding smooth without overshooting.

Tetris was designed by Alexey Pajitnov and first released in 1984 on the Elektronika 60 at the Soviet Academy of Sciences. It reached Western audiences mainly through Nintendo bundling it with the Game Boy at the handheld's 1989 launch. About 35 million units sold with Tetris as the pack-in game. The puzzle design is simple on its surface. Seven shapes, four rotations each, one goal. No tutorial needed, and it stays engaging at high speed.

The core improvements in Forge Drop, like the 7-bag randomizer, the SRS wall-kick system, and the lock delay grace period, were standardized in the early 2000s through The Tetris Company's Tetris Guideline. These changes made tournament play more consistent and skill-based. Forge Drop applies those rules cleanly, without a hold piece or T-spin bonus scoring. That makes it closer to the competition-focused guideline spec than to more feature-heavy commercial versions.
