The Core Loop
The Rule
Balls carry a number from one to nine. Land them so a touching group adds up to exactly ten and the group clears. That is the entire rule, and it never changes.
The Pit
Between your finger and the floor sits furniture: pins that deflect, stones that clog, sloped floors, chutes that carry a ball somewhere else. Aim is a guess you get better at.
The Pressure
The pit is not waiting politely. On a clock that tightens as you climb, a new row pushes up from the floor. Clearing drains it. Hesitating does not.
How you lose: material stacks past the danger line near the top of the pit. You are never killed by a single bad drop — you are buried by twenty of them, which is a slower and more personal way to lose.
Features
-
49 Hand-Built Pits Nothing is generated. Every pit was placed by hand and played until it was fair, then ordered across ten chapters so each one teaches exactly one new thing.
-
Ten Mechanics, One at a Time Pins, stones, shaped floors and chutes. Then the pit starts to move — sweepers slide, bumpers kick, ramps throw one fixed way, teeters rock so it matters when you land, clusters orbit a hub, and spouts burst balls in sideways from the wall.
-
Three Endless Modes Each one drawing only on what the campaign has already taught you, so an endless run never asks a question you have not been shown the shape of.
-
52 Leaderboards One for every pit and one for every Endless tier, through Game Center. Progress syncs through your own iCloud account.
-
No Ads, No Energy, No Sign-In The first sixteen pits and Endless I are free. One optional purchase unlocks the rest, once. Nothing else is ever sold to you.
