expert 10 colors

Zoodoku Level 199 is an unseeded 10x10 cow board; follow r3c4, r5c1, r6c3, r8c8, r9c10, r4c9, r1c7, r7c6, r2c2, and r10c5 while avoiding red r4c1.

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

Place the first cow at r3c4 in the purple singleton; this starts the visible white X propagation.
Do not count red-probed r4c1; place the second cow at r5c1 in the orange territory.
Place the third cow at r6c3 in the teal territory.
Place the fourth cow at r8c8 in the yellow territory.
Place the fifth cow at r9c10 in the green territory.
Place the sixth cow at r4c9 in the brown territory.
Place the seventh cow at r1c7 in the mauve territory.
Place the eighth cow at r7c6 in the light-blue territory.
Place the ninth cow at r2c2 in the light-green territory.
Finish with the tenth cow at r10c5 in the pink territory, then confirm Unbelievable.

Colors in this level:

Light-green, Mauve, Brown, Purple, Orange, Pink, Light-blue, Green, Teal, Yellow

Do not tap r4c1: the source records it as a red failed orange probe, while r5c1 is the successful orange placement.
Do not reorder the late cells r4c9, r1c7, r7c6, r2c2, and r10c5; their row and column exclusions are visible in the dense frames.

Open with purple r3c4, reject red r4c1, then place orange r5c1 and teal r6c3 before the yellow lower-right cell.
The late close is brown r4c9, mauve r1c7, light-blue r7c6, light-green r2c2, and pink r10c5.

Board notes 5 details

Layout: The 10x10 opening has a broad light-green upper field, mauve across the top-right, brown on the right edge, purple at r3c4, orange and teal on the left, pink through the lower field, light-blue across the center-right, and yellow near r7c9-r8c9.
Goal: Place ten cows in the verified source order r3c4, r5c1, r6c3, r8c8, r9c10, r4c9, r1c7, r7c6, r2c2, and r10c5, using each territory once.
Opening: The first decoded frame has no seeded cow and no opening X. Accepted r3c4 starts the white X propagation; the source then records red r4c1 before the successful r5c1, followed by r6c3 and r8c8.
Danger Zone: Red r4c1 is the failed orange probe and costs one heart; the successful orange cow is r5c1. Keep the red X separate from the white logical X field.
Mechanics: This is an unseeded ten-cow 10x10 board with one red probe; the final capture shows Unbelievable, ten cows, and two hearts remaining.
