How to Solve Sand Blocks Level 278 — Full Solution
- Drag the small cyan receiver below the 11 feed into the upper-left stepped footprint and the purple receiver below 19 into the upper-right step; wait for both fills to clear.
- Feed the pink icy receiver from the left-side 5 chute until its counter reaches 2, while the top counters settle to 8 and 16.
- Place the small green receiver at the right-side green feed, clearing the triangular green pocket and exposing the lower key row.
- Clear the green and pink key-marked bars from the bottom row, then wait for the key to count down and release the white four-lock on the center green L.
- Keep the square beneath the upper-right magenta receiver vacant while the enlarged key travels upward; let it enter the yellow four-lock instead of covering the path with a purple bar.
- After the lock animation, move the center green L into its matching open footprint and clear it to 100%, exposing the central cyan channel.
- Route the cyan L-shaped receiver and long cyan bar through the opened center, then alternate the remaining purple and pink key bars without crossing the yellow divider.
- Finish the last cyan corner and purple bottom pocket; wait until the unlocked magenta receiver clears and the board displays completion.
Colors in this level:
Cyan, Purple, Green, Yellow
Common Mistakes to Avoid
- Parking a purple bar under the magenta four-lock before the key travels upward.
- Moving the center green L before the lower key receivers have released its white lock.
- Treating the key icons as decoration and filling the long cyan bar before the lock chain opens the center footprint.
Quick Tips for Sand Blocks Level 278 (quick clues)
- Keep the yellow center divider and the square below the magenta lock empty until the key arrives.
- Watch 11/19/5 fall to 8/16/2 before moving the green center L.
- Clear the lower green and pink key bars before the long cyan bottom bar.
Board notes 5 details
- Layout
- A cyan feed enters the stepped upper-left receiver at 11, a purple feed enters the stepped upper-right receiver at 19, and a pink side feed enters the icy lower-left receiver at 5. An L-shaped green receiver surrounds the center four-lock; a large magenta square at upper right has a yellow four-lock. The lower half contains cyan L and bar receivers plus green, pink and purple key-marked bars.
- Goal
- Reduce the three feed counters to open the center row, clear four key-marked receivers around the lower grid, unlock the green center L, then deliver the enlarged key to the magenta four-lock before finishing the cyan/purple bottom pockets.
- Opening
- Fill the small cyan and purple receivers beneath their top feeds while feeding pink from the left. The counters move 11/19/5 to 8/16/2; do not cover the yellow center divider or the green side-feed square while the center lock counts down.
- Danger Zone
- A purple horizontal parked directly below the magenta four-lock covers the key landing cell. Moving the center green L into the lower opening before the key animation completes blocks the cyan L-shaped receiver and leaves the bottom key bars unreachable.
- Mechanics
- Four key-marked receivers feed a visible key animation; the center green receiver has a white four-lock, the upper-right magenta receiver has a yellow four-lock, and the cyan/purple/pink counters decrement independently before the lock phase opens the lower grid.
Frequently Asked Questions
Which lock opens first?
The white four-lock on the center green L opens from the lower key receivers; its release creates the path used by the enlarged key to reach the yellow four-lock on the upper-right magenta square.
Where must the key route stay open?
Keep the yellow center divider and the cell immediately below the magenta square clear until the visible key animation finishes.
