About the Parallelogram Layout

The Parallelogram board leans. It has two horizontal sides, top and bottom, but the left and right edges slide off at a matching diagonal, so the whole rectangle looks like it has been pushed sideways and frozen mid-tilt. Each row is offset from the one below it, stepping consistently in one direction, which gives the board a sense of motion even while it sits still. It is a rectangle with attitude, all parallel lines and slanting flanks, more dynamic to look at than a plain square but just as orderly underneath.

At 3 out of 5 this is the trickiest of the geometric set, and the offset is the reason. Because rows shift sideways rather than stacking flush, tiles overlap their neighbors in a staggered, brick-like way, and a tile can be pinned from an unexpected diagonal direction. The two slanted edges still give you reliable free tiles, but the interior is more interlocked than the square's, so reading which side is genuinely open takes a bit more care. It plays with a satisfying tension: clearly structured, yet just devious enough that you have to think before you tap.

How to Clear the Parallelogram Layout

Lead with the two diagonal edges. The slanted left and right flanks are where the offset works in your favor, exposing a staircase of free tiles down each side. Clearing these stepped edges first is the cleanest opening and starts loosening the brick-like overlap in the middle.

Respect the direction of the lean. Every row shifts the same way, so tiles are pinned along that diagonal rather than straight up and down. When you check whether a tile is free, look toward the slant: a tile that seems open vertically may still be blocked by the offset row beside it. Reading the diagonal correctly is the whole skill of this board.

The crux is the staggered interior. Because the rows are shoved sideways, the center tiles interlock with their diagonal neighbors and free up in a chain, where opening one tile often unlocks the next one along the lean. Hunt for these chains and ride them, clearing in the direction the board leans rather than jumping randomly around the middle.

For the endgame, try to collapse the board down the diagonal so the final tiles end up along one slanted edge, fully exposed, instead of locked in the staggered core. Keep an eye out for a single high tile sitting across the offset, the usual culprit that jams a near-win. If the stagger does pin both of a pair, Shuffle re-deals the remainder solvably, so a tangled middle is always escapable.

The Story Behind the Parallelogram Layout

A parallelogram is what you get when you take a rectangle and lean on it, and that gentle shove turns out to be one of the most useful ideas in design and physics. It is the shape of a force diagram, the way engineers add two pushes into one; it is the slant of italic type, the lean of a fast-forward icon, the stripe of a racing decal. The whole point of the form is implied movement: parallel lines sliding past each other, suggesting speed and direction even on a static page.

That built-in sense of motion is exactly why it makes a livelier Mahjong board than its upright cousins. The diagonal offset means the tiles overlap like staggered bricks, creating those satisfying chain reactions where one match leans into the next. Where the square is calm and balanced, the parallelogram has momentum; clearing it feels less like dismantling a wall and more like letting a leaning stack of tiles cascade in the direction it was already tipping.

Frequently Asked Questions

What makes the Parallelogram harder than the Square or Trapezoid?

The sideways offset between rows. Tiles overlap their neighbors diagonally instead of stacking flush, so a tile can be blocked from an unexpected angle. That interlocking is why it rates 3 out of 5 rather than 2.

Where do I start on the Parallelogram?

On the two slanted edges. The lean exposes a staircase of free tiles down each diagonal flank, and clearing those first is the cleanest way to begin loosening the staggered middle.

How should I read whether a tile is free here?

Look along the direction of the lean, not just up and down. Because every row shifts the same way, tiles are pinned diagonally, so a tile that appears open vertically may still be blocked by the offset row beside it.

How do I avoid getting stuck in the middle of the Parallelogram?

Clear in the direction of the slant and follow the chains, since opening one interior tile usually unlocks its diagonal neighbor. Aim to finish along one slanted edge. If you do jam, Shuffle re-deals the remaining tiles into a solvable layout.
