What is Fill The Gap?
Fill The Gap is a strategic block-placing puzzle game developed by MarketJS and released in September 2018. This HTML5 game is designed to test your spatial reasoning and forward-thinking abilities in a clean, minimalist interface. With its mobile-compatible design, the game works flawlessly on both iOS and Android devices, making it the perfect companion for puzzle lovers on the go.
The Core Concept
At its heart, Fill The Gap is deceptively simple: drag and drop blocks to fill gaps on a grid. Complete rows to score points, and complete multiple rows simultaneously to earn bonus points. The game continues until you run out of turns, making it a test of endurance and strategy. As one player put it, “Fans of Tetris and Trixology will love this,” and it’s easy to see why—the game combines the spatial puzzle elements of classic block games with a fresh, engaging twist.
Gameplay: The Art of Block Placement
The genius of Fill The Gap lies in its straightforward mechanics that hide a deep strategic challenge. Here’s how the game works:

The Playing Field
You’re presented with a grid and a set of blocks in various shapes and sizes. Your task is to place these blocks strategically within the grid to create complete horizontal lines. When you successfully complete a row, it disappears, creating more space for additional blocks. The game rewards efficiency—complete multiple rows at once, and you’ll earn bonus points.
Turn-Based Strategy
Unlike traditional block games where pieces fall continuously, Fill The Gap uses a turn-based system. You’re given a set number of blocks to place, and each placement consumes a turn. You must carefully consider where to place each block to maximize your scoring potential and avoid running out of space. This turn-based approach adds a layer of strategic depth that sets the game apart from its competitors.
The Endless Challenge
The game features endless gameplay, meaning it continues indefinitely as long as you can keep placing blocks. There are no levels to complete or time limits to worry about—just you, the grid, and the blocks. This endless format makes Fill The Gap a perfect “just one more game” experience that’s hard to put down.
Controls
The controls in Fill The Gap are intuitive and user-friendly:
- Mouse or Touch: Simply click or tap on a block to select it, then drag it to your desired position on the grid.
- Drop: Release the mouse button or lift your finger to place the block.
- Rotate: Some versions of the game allow you to rotate blocks before placing them, adding an extra layer of strategic planning.
The game’s portrait orientation (540×960 dimensions) makes it particularly well-suited for mobile play, though it works just as well on desktop screens.

Tips for Beginners: Mastering Fill The Gap
If you’re new to Fill The Gap, these strategies will help you get started on the right foot:
1. Think Before You Place
It’s tempting to place blocks quickly, but taking a moment to consider your options can make a significant difference. Look at the entire grid and think about how your current placement will affect future turns. Good planning is the key to success in this game.
2. Clear Multiple Rows
Your goal should always be to clear multiple rows at once whenever possible. Not only does this earn you bonus points, but it also clears more space on the grid, giving you more options for future placements.

3. Keep the Grid Balanced
Try to maintain a balanced grid with blocks distributed evenly. This prevents situations where you’re forced to place blocks in awkward positions that waste space. A balanced grid is easier to manage and offers more strategic options.
4. Focus on the Center
When in doubt, focus on placing blocks in the center of the grid. This gives you more flexibility for future placements and helps maintain a balanced layout. Avoid creating dead zones in the corners where blocks can’t be used effectively.
5. Use All Your Blocks
Before the game ends, try to use all the blocks available to you. Every block placed is an opportunity to score points and clear rows. Even if a block doesn’t immediately seem useful, it might create an opportunity for a later combination.
