How to Play GridSmash
GridSmash is a strategic block placement puzzle played on a 10×10 grid. Each turn you receive three block pieces of varying shapes and sizes. Drag and drop each piece onto the grid to place it — all three must be placed before you receive new ones. Block Rotation: You can rotate any piece before or during placement! On desktop, right-click while dragging a piece to rotate it 90° clockwise. On mobile, simply tap a piece in the dock (without dragging) to rotate it. When you completely fill a row or column, it clears from the board and earns you points. Clear multiple lines simultaneously for combo bonuses. Starting from turn 10, special blocks may appear. Crystal blocks (💎) grant +200 points when part of a cleared line. Ice blocks (🧊) require 2 line clears to remove. Wild blocks (⭐) are golden cells you can place anywhere. Every 10 turns, the Shatter Zone activates on the bottom 2 rows for 3 turns — clear lines there for triple points!
Frequently Asked Questions
What are the different block shapes in GridSmash?
GridSmash features 20 unique block shapes ranging from 1 to 5 cells. These include dots, lines, L-shapes, T-shapes, squares, plus signs, and more. Each turn you get 3 random pieces in different pastel colors.
How do special blocks work?
From turn 10 onward, special blocks may appear with each set of pieces. Crystal (💎) has a 15% chance and clears a 3×3 area when part of a cleared line (+200 pts). Ice (🧊) has a 10% chance and requires 2 line clears to remove. Wild (⭐) has a 5% chance and can be placed anywhere, even on occupied cells.
What is the Shatter Zone?
Every 10 turns, the bottom 2 rows become a golden Shatter Zone for 3 turns. Any line clears in these rows score 3× points. If the Zone expires without being cleared, 3 random cells fill with blocks as a penalty.
How is the score calculated?
You earn 10 points per cell placed, 100 per line cleared (×lines simultaneously), and combo streak multipliers (×1, ×1.5, ×2, ×3, ×5). Crystal block explosions give +200 points. Shatter Zone clears get 3× bonus. Perfect clears (empty board) earn +5,000 bonus!
