Step-by-step solution

Quick answer
  1. 1) Open by selecting the dark block at the tray's bottom line to top off and empty the dark receiver in the far-left lane, which also empties the green receiver in the middle-right lane.
  2. 2) Immediately choose the lower-center yellow block to clear the yellow receiver that the green receiver had been hiding.
  3. 3) Give every surprise bag a wide berth, because no receiver is ready for a random color and a bag spilling red right now would plug the belt.
  4. 4) Check the newly revealed Mystery Boxes after the first wave, and treat whatever color they expose as your new priority target.
  5. 5) If a question box flips to violet or cyan, start pulling the visible violet and cyan stones from the middle of the tray.
  6. 6) Empty the stone sitting right under the yellow key, which trips the lock-and-key and opens the tray's right side and its solid stone blocks.
  7. 7) With the lock gone and several colored receivers now live, lean on them to poke the outer ring, and wait to open another bag until the first one's stones are fully sorted.
  8. 8) In the final squeeze, draw the leftover solid yellow stones from the unlocked right side to clear the deep stacks, keep the belt as a short-term holding zone without passing the halfway mark, and clear the corner bags one at a time to finish.

Level 299 Surprise Bag Ring and Center Lock Trap

This board sits some absolute trap right out of the gate.

one sit staring at one huge diamond-shaped upper rack wrapped almost entirely in grey Surprise Bags .

this colors you actually need are locked up.

gold, emerald, dark, plus light blue dominate the early visible board.

But this real dictator from this match sits that huge gold seal plus pass blind middle, cutting off the access into the right side of the board.

If one start panic-tapping this outermost ring, one shall die into Conveyor Belt overflow in ten seconds.

We hold into surgically dismantle this middle lane into send that pass, show this bottom Mystery Boxes , and survive the midgame.

Level 299 Center Key pattern

Let’s look at this exact nightmare sitting in front of you.

this entire outermost border sits walled off via grey Surprise Bags hiding unknown marble colors.

one hold one handful from solid shades visible on this middle—mostly cyan, yellow, purple, and black.

east on this middle from all this sits the Lock and Key .

this gold pass mechanism stretches into this east, heavily guarding a block of solid colors.

one can't access those east-side marbles until the key drops.

The setup dictates your exact opening moves.

one hold four lanes into manage: Far west lane: dark parked over upper from a Mystery Box , followed by Light Blue.

Middle-west lane: violet covering one Mystery Box , then Green, then Yellow.

Middle-east lane: emerald covering two Yellows, then a Mystery Box .

Far east lane: Light azure covering dark, a Mystery Box , and a Yellow.

this game wants one into choose this Surprise Bags since this solid shades one want for Purple and Light Blue are buried.

Those bags shall dump random marbles onto your Conveyor Belt .

Since the head cases sit highly restricted into dark, violet, emerald, plus Light azure, any stray crimson or amber marbles will instantly jam your line.

this entire priority sits matching this available lower head line using this absolute lower line from this upper rack to carve a path to the key.

Level 299 Level Overview

one hold into empty this junk on the front before the board opens up.

Level 299 Carving the Center

the first taps dictate whether one win or lose.

one want into send this pieces holding onto this seal plus pass , but one should empty the bottom Boxes to make room first.

Look at this bottom row of the Top Tray .

one hold accessible Yellow, Green, and Black marble blocks.

choose this dark piece first into fill plus empty this head Black Box in the far-left column.

This clears this head Green Box in the middle-right column.

Clearing that emerald Box exposes a Yellow Box underneath it.

Immediately choose this lower-middle gold piece in the Top Tray to clear it.

Keep the hands entirely away from the Surprise Bags .

one have zero open Boxes for random colors.

If one bag dumps crimson east now, the Conveyor track will clog and you are dead.

Look at this spaces one just cleared in the Top Tray .

one should now hold one path leading upward toward this tile holding the yellow key.

Level 299 Surviving the Mystery Box Midgame

Clearing that first wave fundamentally changes this board.

this left side drops, revealing a Mystery Box .

this middle-east drops, bringing up another Yellow Box .

Check the newly revealed Mystery Boxes .

Whatever shade they expose is your new priority target.

If this secret case uncovers violet or Light Blue, you are in luck.

one may now start picking off this visible violet plus Light azure pieces in the center of the Top Tray .

empty the block directly underneath the yellow key.

Once that piece falls, the Lock and Key triggers.

this east side from the Top Tray is now unlocked.

one atlast hold access into this solid shade pieces previously held hostage by the lock mechanism.

using this seal gone plus multiple different colored cases now available over this lower, one atlast hold this safety net needed into touch the outer ring.

Wait plus watch what shades dump onto the Conveyor Belt .

Never choose one second Surprise Bag until this spheres from the first one are completely sorted.

Level 299 Managing the Final Column Squeeze

The late game gets highly claustrophobic.

one shall hold deep lanes on this lower cases requiring very exact shades, mainly gold, Light azure, plus whatever the final Mystery Boxes turned into.

Shift the focus to the deeper bottom rows.

one hold one thick tier from gold cases stacked on the middle-left and far-right columns.

bring this remaining solid gold pieces from this unlocked east side from this Top Tray to clear these deep stacks.

Use this Conveyor Belt as a temporary holding zone.

If one Surprise Bag dumps two shades one want plus one one don't, let this bad color sit on the belt.

Just ensure one never let this belt fill past the halfway mark.

Pick off this remaining upper corner Surprise Bags one by one.

via this point, one should hold enough empty cases rotating on into catch whatever random shades the game throws at you.

Frequently Asked Questions

What is the main trap to avoid in Level 299?

The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.

How should I open Level 299?

Ignore this upper layers and aim at this bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.

When does the midgame color change happen in Level 299?

After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.

Any tip for finishing Level 299 clean?

Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
