Fours
What is this game?
Fours is a deeply strategic 'Drop & Merge' block puzzle game based on colors or numbers. It targets brain-training enthusiasts obsessed with Tetris variants, spatial planning, and merge puzzles. A single run is highly immersive and endless—as long as you don't die, it can last 10 minutes or more. Players must place randomly generated blocks onto a tight grid, aiming to connect four identical blocks to merge them into a single, higher-tier block. It is an ultimate mental battle against spatial depletion.
How to Play
Played on a fixed grid (typically 5x5 or similar), the game displays upcoming blocks at the bottom (sometimes single, sometimes pairs). You tap an empty grid slot to place the block. The core mechanic: when 4 (or more) identical blocks touch horizontally or vertically, they collapse and merge into a single higher-tier block. Your goal is to continuously merge for the highest score or block tier. The win/loss condition is 'spatial survival': if poor placements fill the grid entirely and no new blocks can be placed, it's Game Over. As you create higher-tier blocks, board space becomes suffocatingly tight, requiring rigorous calculation for every single move.
Beginner Tips
- Grouping like with like is the supreme rule. Always place identical blocks adjacent to each other. Never leave a red block isolated between blue and green ones.
- Watch the merge anchor point. When 4 blocks merge into 1, the new block usually spawns exactly where you placed the triggering piece. Use this to position high-tier blocks.
- Don't greedily stuff the edges. Prioritize keeping the center cross-channels open; otherwise, when dual-blocks appear, you won't be able to rotate or fit them, causing instant death.
- Always watch the 'Next' queue. If the next piece is yellow, your current move should intentionally leave an open slot that will perfectly complete a 4-match for that yellow.
- Corners are sanctuaries for high-tier blocks. Once you merge the highest current block on the board, try to force it into one of the four corners so it doesn't block traffic.
Advanced Strategy
Predictive Chain Collapse (Combo): Look beyond one move. Intentionally arrange 'three level 1s surrounding three level 2s.' Placing the fourth level 1 triggers a merge into a level 2, which immediately triggers the surrounding level 2s to merge, clearing massive space instantly.
The Landfill sorting method: When forced to place useless, mismatched blocks, designate one outermost edge row as the 'trash can.' Dump junk blocks there to maintain purity in your main combat zone.
Rotate to break gridlocks: If a dual-block doesn't fit, tap it to rotate first. Sometimes a piece that won't fit vertically fits perfectly horizontally, triggering a life-saving merge.
Common Mistakes
Placing a high-tier block dead in the center of the board. This acts like an indestructible statue in the middle of a highway, slicing your board into four disconnected dead-ends.
Panicking and randomly dropping pieces because you got three junk blocks in a row. This destroys your carefully laid '3-out-of-4' setups, eventually causing a fatal mismatch gridlock.
Only staring at the current piece being placed, completely ignoring the life-saving piece in the 'Next' queue, and blocking the exact slot needed for that upcoming piece.
Who is this game for?
An extremely hardcore spatial logic puzzle. Ideal for deep thinkers, fans of 2048 or 1010!, and high-IQ players with an obsessive need to maintain organized, uncorrupted spaces.

1010! Block Puzzle
Also involves placing randomly given shapes into a strictly limited fixed grid, heavily testing your ability to maximize and plan extreme spatial limits.
Threes! / 2048
Though controls use swiping, the core mathematical logic of 'gathering low-tier identicals to collapse them into a high-tier item' to free up space is completely identical.
Merge Block
An outstanding representative of drop-and-merge block games, requiring you to gather specific quantities of colored blocks to avert gridlocked disasters.
