Shale Falling Blocks

Shale forms one thin layer at a time. Here you lay the layers yourself with seven kinds of carved stone, from a sunlit riverbed down to a caldera, and every row you complete is pressed away to make room for the next.

Turn and drop falling stones, clear full rows and tamp the well when holes pile up. 48 campaign stages, endless, a daily seam and online duels.

Stones of four squares fall into a well ten columns wide. Slide and turn each one before it lands; a row with no gaps clears and everything above it drops. The queue shows the next stones, Hold keeps one for later (once per stone) and the outline at the bottom shows where the stone will land. A stone that touches down still slides and turns for half a second, up to fifteen moves. Clearing four rows at once is a Slab and scores the most; turning a stone into a slot it could not drop into is a Spin; clears on consecutive stones build a Chain. Every ten lines you clear charge the tamp: spend it and every column packs down into the gaps under it, then the rows that became full clear. On a touch screen, drag sideways to slide, tap to turn (right half clockwise, left half the other way), drag down to drop slowly, flick down to drop at once and flick up to hold; the Hold and Tamp buttons sit under the well. In a duel every clear of two rows or more pushes rubble rows into the rival's well, and their clears push rubble into yours; the first well to overflow loses the round.
