Which cell is seeded in Level 128?

The first frame shows a panda fixed at r1c1, with row-1 and column-1 opening Xs around it.

Which right-edge cell costs a heart?

The source taps r5c9, which becomes a red error X; the legal right-edge placement is r5c10.

The final panda goes to blue-gray r3c6, after r5c10 and r2c9, with two hearts remaining.

Zoodoku level guide

expert 10 colors

Zoodoku Level 128 is a 10x10 seeded-panda board anchored at r1c1; follow r4c3, r6c2, r7c5, r8c8, r5c10, r2c9, and r3c6 while avoiding red-error r5c9.

If the player asks you to sign in, open the video on YouTube instead.

Keep the seeded panda at r1c1 and preserve the opening X wall across row 1 and down column 1.
Place the second panda at r4c3 in the magenta upper-left pocket; its diagonal exclusions leave yellow r6c2 open.
Place the third panda at r6c2 in the yellow left lane; its eight-neighbor ring preserves orange r7c5.
Place the fourth panda at r7c5 in the orange center region; its row and diagonal marks keep purple r8c8 legal.
Place the fifth panda at r8c8 in the purple right-middle region; its propagation leaves the far-right teal cell available.
Do not copy the source's red tap at r5c9; it costs one heart and places no panda.
Place the sixth successful panda at r5c10 in the teal right-edge region, one column beyond the red error.
Place the seventh successful panda at r2c9 in the dark-magenta top-right pocket; its row and column exclusions leave blue-gray r3c6.
Finish with the eighth panda at r3c6 and confirm the two-heart completion state.

Colors in this level:

Light-green, Yellow, Magenta, Blue-gray, Dark-magenta, Teal, Orange, Green, Purple, Brown

Do not use r5c9 as a substitute for r5c10: the source marks r5c9 red and the successful panda is one column farther right.
Do not erase or reinterpret the opening Xs on r1c2-r1c10 and c1; they are logical exclusions from the seeded r1c1 state.

After seeded r1c1, take the magenta r4c3 and yellow r6c2 before the orange r7c5 and purple r8c8 center-right placements.
The right edge is ordered r5c9 (red mistake in the source), r5c10 (legal teal panda), r2c9, then r3c6; do not swap those cells.

Board notes 5 details

Layout: The 10x10 opening has seeded panda r1c1, white Xs across row r1 and down column c1, magenta upper-center pockets, blue-gray top-center, dark-magenta top-right, teal on the right, orange through the center, green lower-left, purple right-middle, and brown lower-right territories.
Goal: Build from r1c1 and reproduce r4c3, r6c2, r7c5, r8c8, r5c10, r2c9, and r3c6; the decisive right-side handoff is legal r5c10 after the red r5c9 trap, followed by the final blue-gray r3c6.
Opening: The first decoded frame shows seeded panda r1c1 and opening white Xs at r1c2-r1c10, r2c1-r2c2, and r3c1-r10c1. Each accepted placement then propagates row, column, territory, and eight-neighbor X exclusions.
Danger Zone: The source's false tap r5c9 becomes a red error X and removes one heart; leave it empty and use teal r5c10 one column to the right.
Mechanics: This board combines a corner seed, a complete opening row/column X wall, a late right-edge red error, seven successful post-seed placements, and an eight-panda finish with two hearts remaining.
