Wall Breaker decides your run with two numbers that move in opposite directions. Brick hit points grow every round, and your ball count grows only when a power up happens to spawn. Read the layout rules below, because the aim line alone will not save you once the numbers cross.
How a row is built
Every round does three things in order. All existing blocks and power ups shift down one row. A fresh row appears at the top. Then the game checks whether any block has reached row 15, and if so the run ends.
The fresh row holds between 2 and 7 blocks. The upper limit is 2 plus the round divided by 3, so rounds 1 through 3 top out at 2 to 3 blocks, and round 15 onward can fill all 7 columns. Column choice is uniform without repeats, so early rows are sparse and late rows crowd.
Hit points start at the round number and add up to the floor of half the round in bonus. A round 1 block has 1 hit point. A round 6 block carries 6 to 8. A round 10 block carries 10 to 14. Each ball contact removes exactly 1 hit point, and the block shows its current total on its face, colored green at a quarter health, yellow at half, orange at three quarters, and red above that.
The 15 row budget and what it implies
The play field between the top offset and the bottom line holds 15 block rows. A block that spawns at row 0 ends your run 15 rounds later if nothing destroys it. You cannot clear everything, so the game is triage.
Use the color bands as a triage queue.
1. Red and orange blocks are your sunk costs from earlier rounds. Ignore them unless they sit within three rows of the bottom.
2. Green blocks near the top die to one ball each. Clear them every round, because cheap kills now prevent expensive descents later.
3. Count rows visually against the dashed red line at the bottom. When the lowest block is inside 5 rows of it, spend the whole volley downward on that column.
Aim mechanics you can measure
The launch angle accepts only upward directions, clamped to 0.15 radians from horizontal, about 8.6 degrees. That clamp is a weapon. A shot at the near horizontal extreme skims the field, bounces off side walls, and can strip several low health blocks in one pass. The preview line draws up to 60 dots at 8 pixel steps, reflects off the side walls, and stops at the ceiling or the first block it enters.
Two facts about the preview change how you should read it.
1. It stops at the first block hit. Anything after that bounce is invisible, so banked routes beyond the first target are a bet, not a plan.
2. It does not simulate ball speed or the launch stagger. Balls leave 0.08 seconds apart at 600 pixels per second, so a volley stretches about 48 pixels per ball down the same path.
The keyboard offers finer control than a single tap, with angle steps of 0.05 radians on the arrow keys and space to fire.
The first ball picks your next position
This is the mechanic most players never notice. When the volley ends, your next launch point becomes the landing spot of your first ball to fall, clamped between 30 and 510 on the width. Your aim choice this round is also your position choice next round.
Apply it deliberately.
1. Before firing, decide which column you want to shoot from next round, typically under the weakest cluster or the column holding a plus one power up.
2. Aim so the first ball does its work and then falls in that column. Side wall banks are the reliable way to steer a landing.
3. Avoid parking under a tall red column. A launch point under heavy bricks wastes the next volley on armor.
Power ups and the arithmetic of survival
Each new row has a 50 percent chance to place a plus one ball in a random empty column. A ball touching it adds one to your volley, permanently for the run. Expected ball growth is half a ball per round, while average block hit points grow by about 1.25 per round times the block count. The deficit is real. Runs die when triage fails, because no aim line outpaces that arithmetic for long.
Treat power ups as primary targets when they sit in the lower half of the field, and as bonuses when they sit high. A ball count above 10 lets you split attention, spending most of the volley on triage and one banked ball on the pickup.
Honest limits of this strategy
The layout rolls are random, and some rounds offer nothing weak. The preview stops at the first block, so deep banked shots fail in ways you cannot audit beforehand. The first ball rule also means an early mistake compounds, since a bad landing spot costs you a full round from a bad angle. And the loss check runs after the shift, so a block at row 14 gives you exactly one round to destroy it, whatever your plans were.
Checklist before your next volley
1. Read the bottom three rows first and mark your triage target.
2. Clear green blocks near the top every round.
3. Choose your first ball landing column before choosing the angle.
4. Use the near horizontal clamp for skimming shots along sparse rows.
5. Take plus one pickups in the lower half on sight.
6. Check the dashed line, and treat any block inside 5 rows as an emergency.
What round do you usually reach, and how many balls do you hold when the wall wins? That pair of numbers tells you whether your runs die from triage or from missed power ups.
