Twenty-five cells
Two identical planes become the next level up
The battle board is 5 cells by 5 - 25 slots - and all 130 planes in the card file carry a combine count of 2. A merge therefore always consumes exactly two identical fighters and returns one of the next level, and every family runs from level 1 to level 10. Machine Gun is the basic one: 37 hit points and 2 damage at level 1, 9634 hit points at level 10. Beside it sit Shotgun, Double Barrels, Small Rockets, Flamethrower, Shield, Booster, Bubble Gun, Fireball, Laser gun, Rocket and Torpedo, tagged Common, Rare, Epic and Legendary.
Observed 2026-10-04 in Chrome: both counters read 0, the level strip runs 1 to 10, and a pair of identical tiles is being pulled together on the 5 by 5 board while the meter under it reads Power 30.
The barrels are the real clock
Ten biohazard barrels (blockStoneNum = 10) sit on the board from the first second, and the price of clearing them climbs: 2000, 3000, 4000, 5000 and then 6000 for each of the last six. The layout puts them on the left and right columns, which is why the working area of a 5 by 5 grid feels like a narrow lane at the start. The Shield family exists for exactly this kind of squeeze - it deals no damage at all, has 135 hit points at level 1 and 42976 at level 10, and its own note reads high HP.
One boss every ten levels
400 stages, 40 of them boss stages
The level file holds 400 entries, and exactly every tenth one - 10, 20, 30 and so on up to 400 - carries a boss. That is 40 boss stages out of the campaign. The tracker across the top shows ten numbers per page and ends the row with a skull, so the tenth number is always the boss you are walking toward and the ninth is the last ordinary stage before it.
What a clear actually pays
Level 1 clears for 500 coins against a base reward of 10, and the level spacing numbers - line step 3, colour step 1, score step 1 - decide how tightly the tiles arrive. Winning doubles the take, because the success reward ratio is 2.0, and the share reward is worth 2000.
Reward boxes are the other coin source: one is worth between 300 and 888 coins, appears for 90 seconds at a time, and pays double if you take the ad version of it.
Coins, dice and bars
Where the coins actually go
Barrels are the expensive purchase, not the draw. A draw costs 3000 coins, four special draws are tracked separately, and the prize list behind the ticker is small money: Coins +400, Coins +200, Coins +100 and Coins +50, weighted 20, 16 and 15 against each other. The wheel spins at 1080 degrees and will not resolve inside 2 seconds.
Damage bonuses add up in small steps
The buff table is short and it is all percentages: Damage plus 7 per cent, plus 9, plus 11 and plus 13. The Booster family is the one that shares instead of shooting - it deals no damage itself and its note reads adjacent fighters, damage plus 7 per cent - so it is worth keeping next to whatever is actually firing.
Clearing a stage also unlocks the next ten on the tracker, since the strip is stepped in tens (main UI level step 10), and the board sizes itself to a portrait canvas of 750 by 1334.
Merge board FAQ
Merging, barrels and the 400 levels
These answers stay with what the board and its config actually carry: two identical planes per merge, ten barrels you pay to remove, and a boss every tenth level.
What should my first move on the board be?
Find two identical planes and pull them together. Every plane in the card file has its combine count set to 2, so a merge always consumes exactly two identical fighters and returns one of the next level up - there is no three-in-a-row variant to look for.
Why does the board feel so cramped at the start?
Ten biohazard barrels are sitting on the 25 cells. They leave the middle and part of the edges usable, and clearing them is priced in coins at 2000, 3000, 4000, 5000 and then 6000 each. Until some are gone your working space is much smaller than the grid suggests.
What is the meter under the board?
It is labelled Power and read 30 in every frame we captured, next to a free dice card. The buff table behind those bonuses is short and explicit: Damage plus 7, plus 9, plus 11 and plus 13 per cent.
How long is the campaign?
400 levels, and exactly every tenth one carries a boss, which makes 40 boss stages. The tracker at the top shows ten numbers per page and closes the strip with a skull, so the last number on the row is the boss.
