Every bin carries a stripe on its head, and every parcel must land where that stripe allows. Welcome to 21 com, a sharp rule-based puzzle game where planning, logic and flawless execution lead to big wins! THE SHIFT A shift starts with parcels stacked in intake lanes and a row of bins waiting at the top of the yard. Tap a parcel, then tap its matching bin, or drag it across. A bin that cannot accept the parcel sends it back, registering a mistake. Clear every lane to complete your shift and keep your 21com winning streak going! TEN RACKS OF RULES 150 shifts are grouped into 10 distinct racks that introduce new mechanics step by step: 01 Color Dock - one color per bin 02 Symbol Lane - bins read the stamped symbol 03 Twin Rules - color and symbol must both match 04 Fragile Bay - heavy parcels cannot follow fragile items 05 Heavy Stack - weight limits and heavy-only bins 06 Hidden Labels - unlabeled parcels reveal their rules upon moving 07 Buffer Shift - a tight bench forces strict order 08 Locked Bins - one bin waits for another to finish 09 Mixed Yard - color, symbol, weight and fragile rules combined 10 Master Sort - every rule active at once THE BUFFER BENCH When a parcel has no immediate landing spot, park it on the buffer bench. A live status line shows your progress, remaining capacity and warns if a dead-end is ahead, helping you adjust your strategy like a 21 com casino pro.
