tap any tile to rotate it 90 degrees clockwise. connect all the pipes into a single network with no loose ends.

tile types

hints

• connected pipes turn green
• no pipe should point off the edge of the board
• every pipe must connect to its neighbors
• use undo if you get stuck
• every puzzle is always solvable

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

pouring

• sand pours only onto the same color
• you can pour into an empty vessel
• all matching layers on top pour at once
• full vessels can't receive more sand

hints

• keep one empty vessel free as a workspace
• focus on one color at a time
• use undo to back out of dead ends
• every puzzle is always solvable

the grid shows a color gradient that's been scrambled. swap tiles to put them back in order and restore the smooth gradient.

swapping

• tap a tile to pick it up, then tap another to swap them
• tiles with a small diamond are fixed anchors — they can't be moved
• tap a selected tile again to deselect it

hints

• start from the corners and edges, which are always fixed
• look for tiles that are clearly out of place first
• trust your eyes — the gradient should look smooth
• use undo to reverse a swap
• every puzzle is always solvable

place blocks on a 9×9 grid to fill rows, columns, or 3×3 boxes. filled groups clear automatically.

placing blocks

• tap a block in the tray to pick it up
• tap a spot on the grid to place it
• blocks must fit — they can't overlap filled cells
• when all 3 blocks are placed, 3 new ones appear

scoring

• 1 point per cell placed
• 18 points per row, column, or box cleared
• clear multiple at once for combo bonus
• consecutive clears build a streak bonus

modes

• endless — play until no block fits, chase high score
• target — reach the target score to win

the grid is filled with arrows pointing in different directions. tap an arrow to release it — but only if nothing blocks its path to the edge of the board.

how it works

• each arrow points up, down, left, or right
• tap an arrow to remove it if its path to the edge is clear
• blocked arrows can't be removed yet — clear the way first
• remove all arrows to solve the puzzle

hints

• highlighted arrows can be tapped right now
• think about which arrow to remove first
• use undo if you get stuck
• every puzzle is always solvable

fill every cell with a diagonal slope — either ╲ or ╱

rules

• the numbers show how many slopes meet at that point
• the slopes must not form any closed loops

hints

• tap or click to cycle: ╲ → ╱ → empty
• right-click places ╱ directly (desktop shortcut)
• corners can only have 0, 1, or 2 slopes
• edge vertices max out at 2 or 3
• use undo if you get stuck

draw edges between dots to form a single closed loop that passes through every circle.

rules

• white circles: the loop goes straight through
• black circles: the loop turns 90°
• numbers show the total length of both arms from that circle

hints

• tap between dots to cycle: line → X → empty
• X marks help you remember where lines can't go
• small numbers are the most constraining — start there
• use undo if you get stuck

draw edges between dots to form a single closed loop that passes through every pearl.

rules

• white pearls: the loop goes straight through, but must turn in the previous and/or next cell
• black pearls: the loop turns 90°, and must go straight through both adjacent cells

hints

• tap between dots to cycle: line → X → empty
• X marks help you remember where lines can't go
• black pearls near corners are very constrained
• use undo if you get stuck
