Merge Balls is a physics puzzle game released by publisher AZGames on October 13, 2026. At first sight, the game looks like a simple, fun ball-dropping puzzle game. But behind that casual exterior is a dynamic physics interaction mechanism that demands sophisticated spatial management thinking.
Progression of the game in steps
Step 1: Observe and Position
- Check: Observe the current ball's colour and the next ball in the preview panel.
- Aim: Move the cursor to position the ball above the cup.
Step 2: Drop and Merge
- Drop: Release the ball and let gravity pull it down into the objects below.
- Merge: Two balls of the same colour touching directly merge automatically into a larger ball of the next level, increasing your score.
Step 3: Trigger Chain Reactions
- Watch: A merge can push adjacent balls into contact and trigger additional merges.
- Control: Watch the shifting pile carefully, as chain reactions may push balls toward the limit line and end the turn.
Step 4: Manage the Limit
- Assess: Check where the merged ball will move other balls before making the next drop.
- Prevent: Choose a landing position that reduces crowding and keeps the pile away from the limit line.
Chain Reaction Momentum Management
Most new players mistakenly believe that Merge Balls is a puzzle game with fixed pieces. In fact, each merge not only creates a larger ball, but also gives off a huge impact force on the surrounding objects.
- The Mass Lifting Phenomenon: When two small balls combine at the bottom, the sudden increase in mass and volume pushes the balls above upwards. If the cup is full, this bounce can easily send the ball over the rim, resulting in an instant loss.
- Controlling Inertia: Instead of dropping the ball freely from a height, drop it near the edge of bigger balls to resist the falling velocity. Avoid uncontrolled vibrations by controlling the friction between the surfaces.

Non-Symmetrical Stacking Strategy for Merge Balls
- Many players try to keep the ball-stacking surface level. This is inefficient as space gets smaller.
- Arrange the balls in decreasing size from one side of the cup to the other. The sloping design acts as a natural “slide” so that newly dropped balls roll automatically to the correct position of the same colour, rather than getting stuck in the middle.
- If you get little balls stuck under big balls, don’t try to shuffle the whole cup. Use the next ball preview to set up the side merge sequence, making room for the balls below to rise by themselves.
The secret to getting high scores in Merge Balls is to control the momentum of the collision and keep the asymmetrical slope structure.
