one rock stack in every row, every column and every color region. rock stacks can't touch, not even at the corners.

how to play

• tap a cell to rake it: that is your note that no stack goes there
• tap again for a rock stack, and once more to clear the cell
• hold a cell to put a stack straight down
• drag across cells to rake a whole run
• stacks that break a rule get a dashed outline. fix them whenever you like
• a finished row, column or region gives its stack a little hop

hints

• a region squeezed into one row or one column settles that line at once. start there
• every cell touching a stack is sand, corners too
• check outlines rule problems. hint points out a wrong mark, or settles the next cell logic can settle
• every board can be finished by reasoning alone. no guessing, ever

turn the tiles until every pipe joins one network, with no pipe pointing at a wall or off the board. water fills what is joined to the ringed source.

how to play

• tap a tile to turn it clockwise
• swipe left on a tile to turn it back
• hold a tile to lock it once you are sure. hold again to unlock
• hint turns one tile to its answer

hints

• start at the edges: no pipe may point off the board
• two dead ends never face each other: they would close themselves off
• every board has exactly one answer

tap a vessel to pick it up, then tap another to pour. sort the sand so each vessel holds one color.

pouring

• sand pours only onto the same color, or into an empty vessel
• all matching layers on top pour at once
• a vessel that shakes can't take that pour
• a finished vessel gets its lid

levels

• "level" plays the next board in a ladder that grows from 2 colors to 12
• some levels give you one spare vessel instead of two
• easy, medium and hard are boards of 4, 6 and 8 colors

help

• hint lifts a vessel and marks where it can pour
• + tube adds one empty vessel, once per board
• undo backs out of a dead end
• every board is solvable

each board starts as a smooth color gradient, then the tiles are mixed up. swap them back until it is smooth again.

swapping

• drag a tile onto another to swap them, or tap one and then the other
• the corners never move. tiles with a dot never move
• tap a picked-up tile again to put it down

help

• start from the tiles with a dot and work outward
• hint marks one tile and the place it belongs, for one move
• undo reverses a swap
• "level" plays the next board in a ladder; the first boards are nearly solved

drag blocks onto the 9×9 grid to fill rows, columns, or 3×3 boxes. a full group clears.

placing blocks

• drag a block from the tray; the grid shows where it lands and what it clears
• or tap a block, then tap the grid
• blocks can't overlap filled cells
• when all 3 blocks are placed, 3 new ones appear

scoring

• 1 point per cell placed
• 18 points for one group, more for several at once
• clearing on placements in a row adds a bonus

modes

• endless: play until no block fits. one undo per hand
• target: pass the goal, then play on as long as you like. undo is free

stone spirits walk out of the entrance and keep walking until something stops them. give them skills so enough of them reach the exit before the level runs out.

playing

• tap a skill at the bottom, then tap a spirit to give it that skill
• the number on a skill is how many times you can use it on this level
• the bar at the top shows how many are saved, the level name, and the time
• you win when the number saved reaches the goal

the skills

• scale: climbs straight up walls
• drift: falls slowly, so any drop is survivable
• shatter: blows a hole in the terrain, and is lost doing it
• block: stands still and turns the others around
• build: lays a short staircase upward
• carve: digs sideways through terrain
• delve: digs diagonally downward
• dig: digs straight down

levels

• 32 levels in four tiers: gentle, winding, steep, perilous
• finish a level to unlock the next one
• a finished level keeps its best time and best rescue count

tap an arrow and it slides the way it points. with nothing in front of it, it slides off the board. if something is in the way, it stops there, and now it may be in another arrow's way. clear the board.

how it works

• tap anywhere on an arrow
• an arrow already against something just bumps
• order matters: park an arrow carelessly and it can block the way for good
• if no arrow can move, undo and try another order

hints

• before you slide an arrow that will stop, look at where it will stop
• hint shows a move that still leads to an empty board
• every board can be cleared

• hold an arrow to see its path; slide away to let go
• hint rings an arrow that can leave now
• after your first arrow, a thin ring marks the one that leaves last

fill each square with a slope. each number counts the slopes that touch it.

rules

• each number counts the slopes that touch its point
• slopes never close a loop

hints

• swipe along a square to draw that slope. tap to flip it. hold to clear it
• a corner point touches at most 1 square, a point on the edge at most 2
• hint points at the number that decides the next square and says why. tap it again to see the square
• check says how many slopes cannot be in the answer and can take you back to the last good point

draw one loop through every circle.

rules

• white circles: the loop goes straight through
• black circles: the loop turns
• the number is how far the loop runs straight from the circle, both ways added up

hints

• drag along the dots to draw. drag from a line to erase it. tap between two dots for a line, again for a cross
• crosses mark where the loop cannot go
• small numbers decide the most. start there
• hint points at the circle that decides the next line and says why. tap it again to see the line

draw one loop through every pearl.

rules

• white pearls: the loop goes straight through, then turns right before or right after
• black pearls: the loop turns, then runs straight for two steps each way

hints

• drag along the dots to draw. drag from a line to erase it. tap between two dots for a line, again for a cross
• crosses mark where the loop cannot go
• hint points at the pearl that decides the next line and says why. tap it again to see the line
