Illustration of two six-cell workshop rails, with orange and steel pieces and a two-cell piece waiting below. — Six cells per rail. A little room makes a difference.

A shift is yours to shape.

01 / DRAW

One piece at a time.

Each shift has a freshly shuffled bag: four 1-cell, four 2-cell and four 3-cell pieces. Drawn pieces do not go back.

02 / PLACE

Find the right fit.

Tap a rail with enough room for the whole piece. Every occupied cell earns 1 point. Fill either rail for an extra 4; fill both to lock all 20.

03 / LOCK

Leave with your points.

After placing, draw again or lock the shift. Once you draw, you must place before locking. No room on either rail means zero for this shift; earlier locked scores stay safe.

Six shifts. One order.

Three targets, the same rules and the same fair bag. All are available from the start. Finish all six shifts, even if you reach your target early.

First order

Find your rhythm.

Workshop order

Watch the gap to your target.

100

Bold order

An optional challenge.

Know what the numbers mean.

“Next piece fits: 5 / 7” means five of the seven pieces left fit at least one rail on the next draw. It is not your chance of completing the order.

Your own little workshop.

No timer, account, ads, in-app purchases or analytics. Play offline. Your current piece, bag, scores and preferences stay on your iPhone. Come back to the same order, or start fresh after seeing your six-shift receipt.
