The steel ball bounced right off.
Which ball does this tower need?
You pull back as far as you can, and the steel ball hits a red brick and just bounces away. Red text on the screen — No effect. Choosing among BlockMaster balls comes down to what the tower is built from. Hit the same spot with the wrong ball and nothing happens.
This story is about BlockMaster balls: how twelve balls and fifteen materials fit together, how the game points you to the right ball, and which ball to reach for with each material. It’s all taken from real gameplay screens and the numbers in the game’s matchup table.
Matchups — one number for every ball and material
The game has a ball × material table. Every pairing gets one number — 1.0 is normal, higher breaks more easily, lower breaks less.
- Below 0.62 — it doesn’t work. No effect pops up where it hit.
- 1.25 or more — “it met its match”. The hit effect steps up, and the ball’s card gets a marker.
The screen beside this is level 8, the moment the steel ball hits a brick. The steel-ball/brick pairing is 0.16 — it barely works.
Where the steel ball works and where it doesn’t
| Material | Steel |
|---|---|
| Paper | 1.30 |
| Wood · Plastic · Glass · Ice · Bomb | 1.00 |
| Tempered glass · Sand · Clay | 0.28–0.34 |
| Sponge | 0.20 |
| Brick · Stone · Iron · Rubber | 0.16 |
| Concrete | 0.12 |
That’s why the steel ball is enough through level 5 (only wood and plastic show up). From level 6, bricks and stone join in and The steel ball can’t break brick or stone appears. On top of that, the steel ball weakens as you level up — from level 21 it’s down to 40% power. That’s when the game of choosing your ball begins.
How the game points to the right ball
When a level starts, you pick two of the balls you own. Two things are worth watching.
- The Tower row — above the ball cards, the materials this tower is made of appear as small chips.
- The marker on a card — a ball card gets a marker if it matches at least one of those materials at 1.25 or higher.
The always-free steel ball joins your two picks, making three shots. Balls only get used up when you fire them — just picking them costs nothing.
A prescription for each material
| If you see this material | Reach for | Matchup |
|---|---|---|
 Concrete | Drill | 1.70 |
 Iron | Magnet | 2.00 |
 Stone | Quake | 1.75 |
 Brick | Wrecker | 1.55 |
 Glass | Ghost | 1.45 |
 Ice | Ice | 1.45 |
 Rubber | Ice · Laser | 1.25 |
 Plastic | Multi | 1.70 |
 Paper | Laser | 1.70 |
 Wood | Bomb | 1.30 |
 Bomb block | Bomb | 2.00 |
| Sand · Tempered glass | Sonic | 1.70 · 1.65 |
| Clay | Blade | 1.75 |
 Sponge | None — every ball is 0.5 or lower | ≤0.50 |
Drill — punch through concrete
At level 8 the game tells you Hard blocks? Try the Drill ball. The Drill ball unlocks at level 6 for 35 coins, and it scores 1.70 against concrete.
Ice — freeze it, then shatter it
The Ice ball unlocks at level 3 and is the cheapest ball at 25 coins. It scores 1.45 against ice, and 1.25 against rubber too.
Three “only answers”
- Sand — striking it only scatters it. Only the Sonic ball, which “shakes wide instead of striking”, works (1.70).
- Clay — it isn’t hard, it’s soft. “Only a blade gets through it.” The Blade ball scores 1.75.
- Sponge — there’s no answer. Don’t try to break it; cut away what’s underneath or push it sideways off its support.
Five lines for picking a ball
- Read the Tower row first. The material decides the ball.
- A card with a marker matches at least one of the tower’s materials at 1.25 or higher.
- If No effect appears, change balls. The same ball again gives the same result.
- Sand needs Sonic, clay needs Blade, iron needs Magnet. Memorize these three.
- Don’t try to break sponge. Push it, or cut what holds it up.
The next story is about the three-shot budget — how the number of shots it takes changes your stars and coins.
