Seven Balance

Seven Balance is an offline puzzle about arranging a given set of numbers across seven windows on a steel cabinet laid on its side as a short beam. You place every value by hand. You also move a rest token from window to window. A layout locks only when the left shoulder and the right shoulder share the same moment. Moment means the number in a window multiplied by how far that window sits from the rest. Nothing is drawn for you. The work is choosing seats and a rest so both sides of the beam agree. The campaign is thirty fixed levels in three chapters. Open Span is the plain lever: seven independent windows and one movable rest. Welded Bays joins some neighboring windows so those values must stay together when you rearrange the row. Root Shoulder keeps the moment rule and adds a digital-root condition on one side of the rest. Each level starts with a briefing that shows the number set, the chapter rule, and what a successful lock looks like. After you leave the board, an outcome ledger records whether the lock held and how many edits you used. When a layout locks you can keep it on a shelf with a short personal note. The progress atlas collects failed lock attempts and boards you returned to, so you can see which distances you misread. Away from the campaign, Free Beam lets you assemble your own number set, try rests, and store those sessions. Seals mark how few edits a campaign lock needed. Sound can be quieted in a small workshop screen. A short onboarding walks through placing numbers, moving the rest, and reading left and right moments. All of this stays on the device. The app stores chapter and level progress, seals, layout snapshots and notes, fail and repeat counts, sandbox sessions, the sound setting, and the fact that onboarding was finished. There is no account, no sign-in, no network use, no purchases, and no advertising. Portrait only. English interface. The cabinet styling is only steel windows and a sliding rest. You are not adding columns toward a target sum. You are balancing two shoulders around a point you choose. If you like planning a small set of weights and then testing one rest after another, the campaign levels and Free Beam are the whole product.
