Connect Master Level 140

Start with Reptiles because the scaled, cold-blooded creatures are immediately distinct from humans and rabbits. You'll spot a frog in a leather jacket, a frog with glasses and a stethoscope, another frog with office attire, and a reptilian creature with dramatic eyes. None of these are mammals, so they're bulletproof. Locking in Reptiles early removes four tiles and clarifies the remaining board.

Next, tackle Items That Rust. Once you accept that the puzzle includes a non-character category, the hammer, nail, door handle, and pliers are unmistakable. They're metal, they oxidize, and they're not alive. This second quick win shrinks your problem space significantly.

Finally, grab Rabbits with Party Hats because the celebratory headwear is visually loud and impossible to miss. Even if you second-guess the outfit colors or the specific shade of the rabbit, the party hat is the anchor. Lock them in and move forward with confidence.

You're now left with four human/animal groups: the two doctor sets, the scientists, and the pig doctors. Start by separating species: humans versus pigs. All human professionals go into one pool; all pigs go into another. This immediately clarifies that Pig Doctors are the four porcine characters wearing medical coats, regardless of whether their clothing is blue or white.

Now focus on the remaining humans. You have doctors and scientists. Compare accessories: does the professional hold a stethoscope (doctor) or chemistry beakers (scientist)? Doctors Wearing Blue all have stethoscopes and blue uniforms. Scientists carry test tubes, beakers, or multicolored chemistry gear. If you see a test tube, it's a scientist. If you see a stethoscope, it's a doctor. This binary choice eliminates guesswork.

Here's where Connect Master Level 140 demands precision: you must distinguish Doctors Wearing Blue from other doctors and scientists using two criteria simultaneously. First, is it a stethoscope (doctor) or a beaker (scientist)? Second, is the clothing predominantly blue? If you answer "yes" to both questions, it's a Doctor Wearing Blue. The blue uniform is essential to that category; a doctor in a white coat belongs elsewhere, but in this puzzle, the doctors are explicitly the blue-uniformed ones.

With Doctors Wearing Blue locked, the remaining human professionals are Scientists. Double-check that all four hold chemistry equipment, wear white coats, and show laboratory gear. If any human professional holds a stethoscope instead, you've made an error—re-examine that tile against your confirmed doctor group.
