The Colourfall Cavern

This is one move only. It does not predict whether you can clear the whole wall.

Select a whole patch of matching crystals connected along their sides. A patch needs at least two crystals. Diagonal contact does not count. Confirm with Remove group. The flower, sun, leaf and star identify the four colours.

Every crystal above a gap falls straight down first. Then, if a whole column is empty, the remaining columns slide left. Crystals keep their colour and symbol. New groups wait for you to select them; there is no refill or automatic chain.

See what moves shows the exact next positions as ghosts, using the same calculation as the move. It gives no best-move advice. A small removal can bring a larger group together.

This original wall has a checked clearing route, but a different sequence may leave a dead end. If no matching neighbours remain, Undo restores the exact previous wall. Restart always returns this same wall. Every legal clearing sequence opens the arch.

Score follows regular SameGame: (group size − 2)², with no clearing bonus. This introduction uses four categories on 6 × 7; regular SameGame uses three categories on 7 × 9 and does not promise a clearable random wall.

Keyboard: Tab to a crystal, arrow keys through the wall, Enter or Space to select its patch. Tab to Remove group to confirm. Escape clears a selection. Control or Command Z undoes. Simple view is fully playable; reduced motion shows direct results. Skip movement ends travel without changing its result.

The lake, stone fins and waterfall remain beyond the actual wall. Clear every crystal, pause at the empty arch, then pass through. Progress saves only on this browser when storage is available.
