Prism Mosaic: Chainburst

About Prism Mosaic: Chainburst

After dark, Glass Row fills with light. Every stall sells charms cut from stained glass and set in brass: a ruby moon, a topaz pennant, a jade seal, an aqua kite, a sapphire tile and an amethyst star. Each has its own outline and its own lead lines, so no colour is ever the only clue.

You set the charms out on a lacquer counter, and the counter has a shape of its own. A swap does not clear at once. You make one swap, the counter holds its breath and shows what it would line up, and then you make a second. Both land together, so a row that only exists because of the two swaps counts too. When one swap is enough, press Release. Take a waiting swap back with Undo whenever you like.

Charms that fall into a new line clear again on their own, and every counter asks for chains of a set depth and a score to match. Each link of a chain lights another bulb on the strings above the street. When a planned move runs three deep, a stall lights up and a paper lantern floats into the night and bursts into coloured glass. Light all four stalls before the counter is done.

Twelve hand-drawn counters come first, from a plain square of wood to a pagoda, a moon gate and a bell tower; after them the shapes return with deeper chains, and tonight's counter changes every day. Every counter can be won, and a hint is one press away. Stars follow your score, and Settings offers more moves or no limit at all.

When one swap is enough, press Release (R). Press Undo (U) to take a waiting swap back.
Charms that fall into a new line clear again: a chain. Win a counter by reaching its chain target and its score.

Frequently asked questions

Why does nothing clear after my first swap?

That is the rule of Glass Row: you plan in pairs. The first swap waits and shows what it lines up. Make a second swap and both clear together, or press Release if one is enough.

What is a Lantern Rise?

When a move you planned sets off a chain three deep, a dark stall lights up, a paper lantern floats up over the market and bursts into stained glass, and the string of bulbs flares. Four deep makes the fireworks twice as big. Settings can turn the flare off.

Can every counter be won?

Yes. Each counter is solved by a computer player before you see it, so a way to win always exists. Use the Hint button, or choose more moves in Settings.
