Block Pop

BlockPop is a modern block-puzzle game where you drag colored shapes onto an 8×8 grid, clear full rows and columns, and chase high scores in two distinct modes: endless Classic and level-based Adventure.

♾️ Classic Mode — Endless

Pure survival puzzle. Three pieces sit in your tray at all times. Place them, clear lines, and keep going for as long as the board allows. There is no level to beat and no timer — only the question of how long you can keep the grid breathing. Your personal best score is saved locally and displayed on the home page, so you always know what you're chasing.

★ Adventure Mode — Puzzle Levels

Every level gives you a score target. Reach it and the level is complete — a new one unlocks with a higher goal and more pre-filled obstacles blocking your path. Fail to reach the target before the board jams, and you can retry that same level. Your current level is stored locally, so you can close the tab and pick up where you left off. Difficulty scales smoothly across an unlimited number of levels.

Core Mechanics

Mechanic Description

Drag & drop Pick up any of the three tray pieces with mouse or finger and drag it onto the board. The piece snaps into place when a valid position is under your cursor.

Live preview A translucent ghost of the piece shows exactly where it will land — and only appears when the placement is legal.

Line clearing Fill an entire row or column to detonate those cells with a particle burst and score bonus.

Combo scoring Clear multiple lines in a single move for an exponential bonus. Two lines is worth far more than two separate clears.

Game-over detection After every placement, the game checks whether any remaining piece can fit anywhere. If nothing fits, the run ends.

Scoring

Action Points

Place a single block 10

Clear 1 line 100

Clear 2 lines 300

Clear 3 lines 600

Clear 4 lines 1,000

Clear 5 lines (max) 1,500

Clearing multiple lines at once is dramatically more valuable than clearing them one at a time — a reward for planning ahead.

The Piece Selection Algorithm

Most block puzzle games pick pieces at random. BlockPop doesn't. Every time your tray refills, a board-aware selection algorithm runs:

1. It scans the board and counts how many valid placements exist for all 37 block shapes.

2. Each shape is scored on board fullness, placement availability, difficulty setting, and (in Adventure) current level.

3. Three shapes are drawn using weighted randomness — favoring shapes that actually fit, but preserving variety.

4. A safety net guarantees the tray is never handed to you with zero legal moves, preventing cheap instant-losses.

5. No duplicates — the same shape never appears twice in one tray.

The result is a game that feels fair and varied instead of punishingly random. Difficulty can be tuned from a single config block at the top of the script (easy / normal / hard), and the algorithm's reaction to a cr

owded board can be dialed up or down.
