Cube Merge Tips: Spread Your Shots, Do Not Fire Down the Middle
Key takeaways
- You drag the cube at the bottom left or right and let go to shoot it into the box.
- Twelve shots all released from the middle ended in GAMEOVER in three of three games.
- Twelve shots released from different positions were still running in three of three games, with scores of 96, 132 and 104.
- Cubes with the same number merge into the next number and raise your score.
The first cube merge tip is to spread your shots: in Stackmelt twelve shots released from the middle ended in GAMEOVER in all three games, while twelve shots released from different spots were still going in all three, with scores of 96, 132 and 104. Cubes that land on the same spot pile up in one column and block the lane.
How the game works
Stackmelt is a 3D puzzle in a tall, phone-style column. A numbered cube waits at the bottom of the lane. You drag it left or right and let go, and it shoots into the box. When it touches a cube with the same number the two merge into the next number, and your score at the top goes up. The game ends when the cubes reach the top.
What we measured
We played in a test browser at 1280 by 800 pixels. In each game we shot twelve cubes, one every 2.2 seconds, either always releasing from the middle or releasing from twelve different spots across the lane. We made three games for each method and looked at the screen after the twelfth shot.
| Method | Games over | Scores of games still running |
|---|---|---|
| Always from the middle | 3 of 3 | none |
| From different spots | 0 of 3 | 96, 132, 104 |
Three games per method in one test browser; the cubes in each game come in a random order, so these are directions, not rules.
What is on the screen
The top shows a pause button and the score. The orange-floored box fills with cubes as you shoot. A pointing hand shows where to drag. The end screen says GAMEOVER, or NEW HIGHSCORE when you beat your best.
4 tips that follow from the numbers
- Spread your shots. Middle-only shots ended three games out of three.
- Match the number. Aim at a cube that has the same number as yours.
- Watch the top of the box. When cubes get close to it, merge before you shoot a new one.
- Restart quickly. A new game takes a single tap on play.
