Brain Test Level 270 Walkthrough: Let’s Feed the Fish in Order from Smallest to Largest
Complete Walkthrough, Step-by-Step Explanation, Common Mistakes
🧩 Level Information
- Level Number: 270
- Problem Statement: Feed the fish in order from smallest to largest
- Difficulty: Normal
🎯 Objective
Clear the stage by feeding the fish on the screen to the big fish 'in order from the smallest to the largest'.
📝 Steps to Solve
- Carefully observe the size of all the fish on the screen and identify which one is the smallest. Judge by silhouette (body size), not color.
- Once you’ve found the smallest fish, drag it to the mouth of the big fish (or the central fish’s mouth) and feed it.
- Next, find the 'smallest one' among the remaining fish and drag it, in the same manner, to the big fish’s mouth and feed it.
- Repeat this process, always feeding the 'smallest remaining' fish on the screen in order from smallest to largest.
- The stage will be cleared if you continue feeding them in order (smallest → medium → larger…) without breaking the sequence until the last one.
💡 Hints
- Focus only on 'body size' and choose the smallest fish, not based on color or flashy appearance.
- Since the size relationships change once a fish is eaten, re-evaluate and pick the 'smallest fish currently left'.
- If you do not succeed, check if you skipped the order during the process (is it in small → medium → large order?) and try again.
🧠 Analysis & Points
This stage is a puzzle that tests observational skills and order recognition. The condition is very simple, 'feed in order from smallest to largest', but with a large number of fish or subtly different sizes, it’s easy to choose based on intuition and make mistakes in order. There’s no hidden trick specific to Brain Test, it purely tests your ability to maintain the order of size. Drags in succession may lead you to mistakenly feed in the wrong size order, so proceed deliberately, considering 'is it the smallest left?' with each one.
🔍 Common Mistakes
- Selecting based on color or appearance flair, and feeding in random order instead of 'smallest first'.
- Choosing small fish for just the first couple and then feeding larger looking fish randomly, breaking the order in the process.
- Overlooking fish with similar sizes and delaying the slightly smaller ones.
- Trying to feed just by tapping and not realizing that dragging to the mouth is necessary.
- Misunderstanding and trying to feed the biggest fish first, attempting a 'largest first' order.
🎉 Advice After Clearing
The stage is cleared once you feed each fish in the correct order from the smallest. The difficulty is not high if you carefully perform size comparisons, making it useful as a practice stage to get used to 'order-based puzzles'. In the next level, problems requiring not only order but also a change in thinking will increase.
