Block Out Levels 938-943: One Divider Board, Then Five Runs of Stacked Shelves

The library now runs to Level 943. 938 through 943 went up as one batch, all six rated Expert, and each one has a page on the site plus a video solution on YouTube. The previous batch was 932-937, so this picks up where that run ended.

The 930s ended with big trays pushed out to the frame edge and the field left thin in the middle. This batch takes the other half of that idea: the trays grow until they own two thirds of the board, and the block field is squeezed into whatever strip is left, either a band along the bottom (940, 941, 943) or a band along the top (942, 939). Only 938 keeps the field running the full height, and there it survives because a single long slider splits the board in two.

That changes the opening move on almost every board. You are no longer hunting for the deepest sink first; you are deciding which of the big trays can be reached at all before the band fills up. The counters reflect it too: 39 in the bottom right of 942 and 36 on the right edge of 938 are the two deepest this run, and both sit inside the part of the frame the trays occupy rather than beside the field.

The six newest boards

Each entry below has the board preview, a link to its own page and the video solution. Watch only as far as the first tray completing, then restart and replay that part yourself before watching the rest.

Level 938

Open the Level 938 walkthrough or watch the video solution on YouTube.

A tall portrait board cut into three columns. The right column is two large purple trays stacked inside orange frames, a 29 above a 15. The middle column is a single orange slider that runs the full height of the frame and is marked 1, so it opens once and then it is finished. The left column is the field: a small orange tray marked 3 tucked under the top counter, three teal vertical sliders below it, then orange and pink and purple and yellow blocks down to the bottom, with a white triangle gate on the lower left edge. The counters read 8 and 18 across the top, 4 on the left, 36 and 27 on the right, 3 on an inner ledge at mid height and 2 and 28 along the bottom. The 1 in the middle is a divider, not a tray you plan around: nothing crosses it, so the left field and the right trays have to be finished separately. Open the 3 at the top left first, then work the field downward and let the 29 and the 15 take what the left column cannot.

Level 939

The field is on top here. A dense band of blue, green, purple and red blocks fills the upper third, with a green L in the top right corner, a white gate block at the very top and a brown tray marked 27 in the upper left. Below the band sits a pink square tray marked 1, and under that a wide blue horizontal tray marked 3 that spans almost the whole width. The bottom strip holds a brown 11 tray in the left corner, a small orange 1 tray in the middle, a red vertical bar and a yellow 2x2 on the right. The counters read 10 on top, 1 and 2 and 23 down the left, 9 and 10 down the right and 27 along the bottom. The 23 in the bottom left is the deepest sink on the board and the 1 and 2 above it are the first counters the left column reaches. Feed the 23 and the 27 first, and treat the 1 and 2 as finishers rather than outlets.

Level 940

Open the Level 940 walkthrough or watch the video solution on YouTube.

Two wide purple trays stacked like shelves fill the top two thirds, a 15 above and a 9 below, each framed in orange and each spanning nearly the full width. The whole block field is the shallow band underneath: orange and pink and red and yellow blocks with a purple L in the middle, a blue key block in the bottom left corner and a white down arrow gate on the very bottom edge. The counters read 27 and 31 across the top, 18 and 7 on the left, 21 and 13 and 1 down the right. This is a pure order puzzle. The 15 has to be filled before the 9, because once the lower shelf starts taking blocks the band underneath has no drain left and the 1 on the right edge is gone before you need it. Keep the band low and let the 9 finish the run.

Level 941

Open the Level 941 walkthrough or watch the video solution on YouTube.

Two large purple trays sit side by side in the lower two thirds, a 15 on the left and an 11 on the right, separated by a single orange frame and both opening upward into the top band. That band is the entire field: blue and orange and red blocks with a pink L, a short teal horizontal slider near the middle and a white gate block in the notch at the top of the frame. The counters read 1 and 8 and 21 down the left, 2 and 28 and 12 down the right, and 25 and 32 along the bottom. The 1 and the 2 are the first counters the field touches on both sides, and spending either early closes the side it belongs to. The 21 and the 12 sit at tray level, so they only do work once a tray has started to fill. Work the 32 across the bottom first and save the small counters for the last blocks.

Level 942

Open the Level 942 walkthrough or watch the video solution on YouTube.

Three trays around one band. A tall purple 8 runs most of the height of the left column, and the right column carries a 14 above a 24 in two orange frames, with a small purple dispenser marked 3 hanging off the right edge beside them. The field is a single band across the top: red, orange, yellow, blue, pink and green blocks with a green L in the middle and a white up arrow gate at the top. The counters read 1 and 12 down the left, 5 and 19 down the right, and 13 and 39 along the bottom. The 39 is the deepest counter in the batch and it sits under the 24, so it only opens once the right column has started to drain. Clear the middle of the band first, fill the 14, and leave the 8 and the 24 for the second half.

Level 943

Open the Level 943 walkthrough or watch the video solution on YouTube.

Two purple trays stacked high and a thin field below. The top shelf is a wide 21, the tray under it a large square 9, and between them and the bottom edge there is only one band of blocks: green and blue on the left, a green L and a yellow stack in the middle, a pink L and an orange column on the right, a red horizontal slider near the bottom and a blue down arrow gate in the bottom left corner. The counters read 22 on top, 19 and 2 down the left, 21 and 17 and 7 down the right and 1 along the bottom. The band is short enough that every block removed changes which counter is reachable. The 2 on the left edge and the 1 at the bottom are both finishers, and the 19 above the 2 is the only large left-hand sink, so open with the 19 and the 21 and keep the two small counters for the final blocks.

What to watch for on these boards

The video is a verified solve, not a script. The useful part is the shape of the board:

• A full-height slider is a wall. When one tray runs the entire height of the frame, the two sides of the board are separate puzzles and neither can feed the other.
• Shelf boards punish the wrong first tray. Stacked wide trays have to be filled from the far side inward, or the outer shelf takes the blocks the inner one needed.
• A short band runs out of counters, not blocks. With the field reduced to one strip, the limit is how many counters that strip can still reach, not how many blocks are left.
• Counters at 1 and 2 are budget, not outlets. Spending one early usually costs you the whole side it sits on.
• A dispenser hanging off the edge is optional. The small 3 on 942 can be left until the end; it never blocks the main run.

How to use the walkthroughs

Every level from 938 to 943 has its own page with the board preview, difficulty rating and embedded video. A method that holds up on Expert boards:

1. Watch only up to the first tray completing.
2. Restart and replay that opening yourself.
3. Keep going alone until you stall.
4. Rewatch from the point your route went wrong, not from the start.
