Woodoku Journey Level 20

Overview

Level 20 is an 8x8 wood-block puzzle board dressed in the Halloween Journey skin, with spider-web decorations in the lower corners and a warm walnut-red tile palette. The objective is not to clear the whole board but to collect exactly four blue gems and four red gems that are pre-placed under select cells. Gems are collected whenever a placed block covers (or "breaks") the cell that holds them. You draw three small wood pieces at a time from the bottom tray and drag each onto any legal empty cell; whenever a full row or column of eight cells is filled, that line clears and opens space again. The overall approach is to prioritize pieces that land directly on gem cells while building compact clusters that can later be completed into clears. This is an entry-level Journey stage and should take roughly a dozen moves.

• Difficulty: Easy
• Estimated moves: 12

Step-by-Step Solution

1. At the start of the level, pause and read the gem layout. The four blue gems sit in a loose cluster: one near the upper-center area (around row 2, column 3), one on the left edge (row 4, column 1), and two paired on the right side (row 4, columns 7 and 8). The four red gems are split: one on the right side near the blue pair (around row 3, column 7), and two on the bottom row (row 8, columns 3 and 5), with the fourth tucked in the middle-left area. The initial tray contains three small pieces: a small L-tromino with a blue gem printed on its corner cell, a plain L-tromino, and a short horizontal zig-zag.

1. Take the L-tromino that carries the blue gem on its corner cell first. Drag it so that its gem-bearing cell lands directly on the isolated upper-center blue gem (row 2, column 3). Place the two remaining cells of the L shape downward and to the right so they occupy empty cells around it. This collects that first blue gem immediately and begins a small stack in the upper-middle area.

1. Pick up the plain L-tromino from the tray and set it against the left edge, around row 4, column 1, so that one of its cells covers the left-edge blue gem. Angle the L so its other two cells extend rightward along row 4 rather than stacking vertically, which keeps your vertical columns open for later line clears.

1. Take the horizontal zig-zag piece and drop it near the right-side blue pair (row 4, columns 7 and 8). The shape has a short horizontal bar with one cell offset below; position it so the bar itself covers both blue gems at columns 7 and 8, and the offset cell fills the empty cell beneath one of them. This should collect the remaining two blue gems, bringing your blue counter to zero within the first few moves.

1. A new tray of three pieces appears once the first three are placed. Watch the counter at the top: you should now see roughly three blue and three red gems left at this point in the run. Continue placing pieces so that each new piece touches or overlaps the cluster you have already built, rather than scattering pieces across distant corners. The goal at this stage is to build a compact block in the center of the board that you can later complete into a full row or column clear.

1. When the next small L-tromino or corner piece appears, place it in the middle of the board around columns 3-4 and rows 4-6, filling the gap between the upper cluster and the bottom-row red gems. This sets up a vertical column (around column 4) that you can finish later with a straight bar.

1. As you place pieces, keep an eye on the red gems on the bottom row (row 8, columns 3 and 5). When a small piece that can sit on row 8 arrives in the tray, drop it so that one of its cells covers the red gem at column 3 and the rest of the piece spreads along row 8 toward column 5. This collects the first bottom red gem and extends row 8 toward a future clear.

1. The piece that carries a red gem on its own corner cell (visible in the mid-game tray) should be aimed at the remaining middle-left red gem. Drag it so the printed red gem cell lands on that gem; the other cells of the L should tuck under the central cluster so they do not waste space.

1. At around the halfway point, the blue counter flips to a checkmark showing 0, and the red counter reads 1. Only one red gem remains on the board. At this point stop chasing clears and focus purely on reaching the last red gem. The tray now shows a small L-tromino with a red gem on it, a horizontal three-bar, and a 2x2 square.

1. Use the horizontal three-bar first. Lay it across the empty row that leads toward the last red gem, filling three contiguous empty cells. This does two things: it opens the 2x2 square's landing zone, and it sets up the L-tromino to drop directly onto the remaining gem.

1. Drop the 2x2 square into the open pocket you created in the center of the board, making sure all four of its cells land on empty tiles. The square is the heaviest piece in the tray, so placing it before the L-tromino avoids the situation where the L blocks the square's only fit.

1. Finish by dragging the red-gem L-tromino so its gem-bearing cell covers the final red gem. As soon as it snaps into place, the red counter drops to 0 with a checkmark, the board dims, and the "WELL DONE" completion text fades in over the tiles. The level is cleared.

Strategy & Reasoning

The core idea behind this level is that gem collection is gated by piece shape, not by board-clearing. Many players waste the opening moves trying to complete rows and columns, but because the gems are sparse and spread across the board, line clears come almost for free once you naturally fill the rows that the gems happen to occupy. The optimal strategy is therefore to read the gem positions first and build a placement order that routes each tray piece onto the nearest uncollected gem, while keeping the filled cells as compact as possible.

Prioritizing the gem-bearing pieces early matters because those pieces explicitly tell you which gem they are designed to collect; the game's level design intentionally gives you the matching shape on the same turn the gem is exposed. If you instead park a gem-bearing piece in an empty corner to "save it for later," you burn the advantage of that turn and force yourself to spend two future moves covering the same gem with a less convenient shape.

Keeping filled cells compact rather than scattered matters because the 8x8 board is small and the tray always gives you exactly three pieces. A scattered layout quickly leaves you with isolated single-cell pockets that only tiny pieces can fill, and when the tray delivers a 2x2 square or a three-bar, those pieces have nowhere legal to go. By stacking pieces around a central core, you preserve long straight runs (especially columns 3 and 4) that a later straight bar can clear in one move, which both scores points and resets the board to keep the run alive.

Tips & Common Mistakes

• Mistake: Placing every new piece as far away as possible to "spread out" and avoid filling the board. Correct approach: build inward. Compact clusters are what let you place the larger square and bar pieces later; scattered cells create dead pockets that no piece can fit.
• Mistake: Saving the gem-printed pieces for a "better" spot. Correct approach: use the gem-printed piece immediately on the matching gem. The shape is handed to you for that exact purpose; waiting only risks the board filling around the gem and making the shape unusable.
• Mistake: Obsessing over row/column clears at the expense of gem collection. Correct approach: collect gems first and let clears happen as a side effect. The level ends as soon as all eight gems are collected, even if half the board is still empty.
