A one-level sorting puzzle ad: every tap is a decision between a matching tray and a three-slot HOLD buffer.
Tapping a free screw sends it to the active tray of its color. Two trays are active at a time and the next one queues in when a tray fills. A screw with no matching tray goes to the HOLD buffer; when all three HOLD slots are full, the run fails. Removing every screw that holds a plate releases it and uncovers the screws beneath. Clearing the board ends on the PERFECT SORT card.
Keep the rule readable in one tap and let the HOLD buffer carry the tension: the board is small, but careless taps fill the buffer quickly.
The shipped playable ad: a single board built around the two-tray rule and the HOLD buffer, ending on the PERFECT SORT card. In the RU hero it opens with the commuter UGC video; from this page it starts straight at the board.
The standalone build opens on a start screen and plays five authored boards in sequence, LEVEL 1/5 to 5/5, each with its own layout. Every clear shows LEVEL COMPLETE → NEXT LEVEL; the fifth ends on DEMO COMPLETE, and PLAY AGAIN returns to the start.
The shipped ad opens with a vertical commuter video. When the phone in the shot fills the frame, a still of the board pinned to the phone screen expands to full screen with a 200 ms clip-path and scale transition while the video fades, and input passes to the live Cocos board. The footage is Russian-language; the handoff layer is independent of the video file.
