Brain Out Level 161

Overview

Level 161 asks you to "Help dog to win!" by finishing a two-horse race against a rabbit. The board shows a dog rider on a brown horse sitting on the upper lane, and a rabbit rider on a white horse waiting on the lower lane, with a bent red finish-line marker on the right and a large blue Start button near the bottom. At first glance the layout looks like a normal race you have to watch, but the dog on the brown horse is visibly slower than the rabbit's white horse, so simply pressing Start hands the win to the rabbit. The Brain Out twist is that you can rearrange the riders before the race even begins, putting the dog on the faster white horse so it crosses the line first. The whole level is solved with one drag plus one tap.

Step-by-Step Solution

1. Before touching the Start button, look carefully at the two horses. The brown horse on the upper track carries the yellow dog, while the white horse on the lower track carries the rabbit in the yellow shirt. In this race, the white horse is the faster one and the brown horse is the slower one, so the dog's current mount loses by a wide margin. Do not press Start yet, or the rabbit will simply outrun the brown horse.
2. Press and hold on the dog rider (the yellow dog sitting on the brown horse) and drag him off the brown horse over to the white horse. Drop the dog onto the saddle of the white horse on the lower lane. The rabbit will end up riding the brown horse once the swap registers. If the drag does not pick the rider up, make sure you touch the dog body rather than the horse body itself; the rider is the draggable piece, not the animal.
3. Watch the swap visually to confirm. After the drag, the dog should be sitting on the white horse and the rabbit should be sitting on the brown horse. If you drop the dog in the empty space between the two tracks instead of on the saddle, the swap will not count and the level will not advance — re-grab the dog and drop him directly onto the white horse's back.
4. Once the swap is confirmed, tap the blue Start button at the bottom of the screen. The two horses will gallop toward the red finish marker on the right. Because the dog is now on the fast white horse and the rabbit is on the slow brown horse, the dog crosses the finish line well ahead of the rabbit.
5. When the dog reaches the finish marker, the level-complete pop-up appears with the professor avatar, the "Congratulations!" banner, and the quip "Ah! A good horse is very important!" Tap Next to move on.

Strategy & Reasoning

The puzzle exploits the assumption that a race is decided by tapping Start and letting the outcome unfold. The dog is not faster than the rabbit, and neither horse is under your control during the race, so the only lever you have is the pre-race setup. By moving the rider onto the faster mount, you change the starting conditions rather than trying to influence the race mid-way.

Alternatives fail for predictable reasons. Tapping Start immediately with the dog on the brown horse just replays a loss. Dragging the finish line or the red marker does nothing, because the marker is decorative. Trying to speed the brown horse up by tapping it during the race also does nothing. The swap is the intended interaction because it is the only way to reroute the fast horse under the correct rider, and the congratulatory line about "a good horse" confirms that the mount, not the rider, was the lever. The horse that looks nicer (the brown one with the dog already on it) is actually the slower one; the white horse below is the secret fast mount, which is the Brain Out habit of hiding the useful object in a secondary position.

Tips & Common Mistakes

• Pressing Start before rearranging anything. The dog loses every time on the brown horse; always pause and inspect the mounts first.
• Dropping the dog in empty space instead of directly on the white horse's saddle. The drag only registers when the rider lands on the second horse, so aim for the saddle area.
• Trying to influence the race after it has started, such as tapping the horses or moving the finish marker. Nothing mid-race changes the outcome; set up the swap before Start.
