Drop numbered discs. A disc clears when its number matches its row or column count.
A 7×7 board sits below a disc with a number from 1 to 7. Tap any column to drop the disc — it falls to the lowest empty cell.
After landing, every disc on the board is checked: if a disc's number equals the number of discs in its row OR its column, the disc disappears.
When discs disappear, the ones above fall down. Then the check runs again — and again — creating chain reactions.
Each chain wave scores more: cleared count × wave depth × 5. Big chains rack up huge points.
The game ends when every column is full and you can't drop the next disc.
Goal: highest score before the board fills up.
The core trick is that a disc vanishes when its number equals how many discs share its row or column, so you are not stacking — you are arming countdowns. A 7 only clears in a completely full line, while a 1 clears the instant it is alone in its row and column, so place low numbers where lines are nearly empty and high numbers where lines are nearly full.
The big scores come from chains, because each clearing wave is worth more than the last (cleared × wave depth × 5). Set up a position where one disc vanishing drops others into their own trigger counts, cascading down the board. Before each drop, glance across the row and column you are landing in and ask what it becomes after the disc settles — and what it becomes again once a clear shortens that line. Patience building a primed board pays off far more than dropping discs to merely survive.
