ARCADE / PARCEL PRISM

Parcel Prism

puzzlescore attacktouchsorting

Tap a lane (or keys 1/2/3) to send each belt parcel down it · HOLD parks the current parcel once per run · AIM HELD then tap a lane to drop it

A finite real-time colour-sort score attack. A belt feeds coloured parcels one at a time; tap one of three lanes (or press 1/2/3) to drop the current parcel onto that lane's bottom-up stack. Three same-coloured parcels mark a ship, but the ship only resolves when the lane fills — so a deliberate two-colour stack like three reds under three blues fires a depth-2 cascade when the sixth parcel fills the lane, clearing six slots at once and banking points times a combo multiplier that grows with every consecutive ship and resets on a dry one. Each run gets one hold swap: park the current parcel and the next lane tap drops it. Every run seeds a fresh 60-parcel belt, and the first three parcels always share a colour, so filling a lane always yields a ship. The clock is 75 seconds, the belt is finite, and a lane that fills with no room for the next parcel ends the run. Reading the upcoming colour and each lane's capacity to set up cascading fills beats blindly hammering a single lane.

How to play

Rules

Tap a lane (or press 1/2/3) to send the current belt parcel onto that lane's stack. Three same-coloured parcels mark a ship, but the ship only resolves when the lane fills — fill a lane with two colours (three of one under three of another) and the fill cascades: the lower trio ships, the stack compacts, and the upper trio ships too. Consecutive ships build the combo multiplier; a placement that ships nothing breaks it. The run ends after 75 seconds, when the 60-parcel belt runs out (cleared), or when no lane can take the current parcel (jam).

Controls

Tap a lane (or keys 1/2/3) to send each belt parcel down it. HOLD parks the current parcel once per run; the next lane tap drops the held parcel.

Tips

A lane only ships when it fills, so stacking one colour on three of another before the fill cascades for two ships. HOLD then tap a lane to drop a parcel where it completes a two-tone fill. Reading the upcoming colour and lane capacity to set up cascading fills out-scores single-lane tapping.

Behind the game

Parcel Prism is a small sorting floor where every tap changes the capacity of the next decision. A belt presents one coloured parcel at a time. Send it to one of three bottom-up lanes. Three matching colours mark a ship, but the ship only resolves when the lane fills — so the real skill is filling a lane with two colours to cascade, not shipping the instant three line up. That sounds restrictive until the stacks begin to fill: a lane holding three reds under three blues pays both groups in one fill, and the board opens up in bursts rather than one parcel at a time. A lane that contains useful colours can also become a trap if it has no room for the parcel now on the belt. The run is finite, fast, and deliberately readable: you are managing three tiny warehouses rather than reacting to a random shower of blocks.

Shipping is where the score accelerates. Consecutive placements that cause a shipment build the combo multiplier; a placement that ships nothing cools it back to zero. Look at the current colour, the next preview, and the height of all three lanes before choosing. Sometimes the right move is to hold a nearly-full lane one more parcel so a second colour stacks on top and the fill cascades. Sometimes it is to fill immediately, free space, and keep the chain alive. The single HOLD slot is a useful exception, not a panic button: park the current parcel once, then choose a lane to place that held colour later. It can turn an awkward arrival into the colour that completes a two-tone fill, but spending it without a plan removes your only reorder tool.

Each 75-second attempt uses a seeded belt of sixty parcels. The first three share a colour, so every run begins with a lane you can fill to ship, while later order and colour pressure change from seed to seed. A run can end because time expires, the belt is cleared, or no lane can accept the current parcel: congestion is a consequence of your layout, not a hidden failure. The prism theme fits the bright logistics puzzle. Colours enter as separate packages, then align into a clean dispatch burst; the best runs make the lanes feel less like storage and more like a rhythm section. Read ahead, leave breathing room, fill in sequence, and keep the belt moving.
