How to Beat the Puzzle in Como Se Llega Chapter 3b Level 1
You need three things for this one: the rusty key you picked up back in Chapter 2, the magnifying glass from the toolbox in the first room of Chapter 3, and patience. Most people get stuck because they try to use the key directly on the locked door without checking the floor first. I wasted about forty minutes on that before I figured it out. Start by examining the floorboards near the fireplace. Drag the magnifying glass to that area and you'll spot a loose plank. Click it once to pull it up, then click again to dig underneath. The rusty key isn't visible on the surface — it's buried in the dirt. Grab it, then head to the locked door at the back of the room. The key works on the first try; there's no combo or riddle attached to it. Once the door opens, you enter a small hallway with two passages. The left one leads to a dead end with a broken shelf. The right one has a puzzle box sitting on a table. Do not pick up the puzzle box yet. Instead, examine the wall behind it and you'll see three colored tiles that don't match the rest. The solution is red, blue, red. Tap each tile in that order and the box unlocks.
Inside the box is a brass gear. Take it and return to the first room where you found the magnifying glass. There's a small machine against the far wall with a missing gear slot. Insert the brass gear and turn the crank on the side. This activates a hidden compartment under the floor near the entrance. Open it to find a flashlight, which you need for the next section. Here's the thing nobody mentions: the game does not auto-save between rooms. If you close the app or your phone dies while you're mid-puzzle, you lose everything since your last save point. I learned that the hard way when a battery warning appeared and I had to force-close, which cost me nearly an hour of progress. Make sure you're at a stable save point before attempting any tricky sequence. The save icon looks like a scroll and appears in the bottom right corner of the screen. Another common mistake is assuming the puzzle box requires the gear first. It doesn't. The colored tile sequence opens it completely independently. You can grab the gear afterward or come back later. The game only blocks the machine in the first room until you have the flashlight, so plan your movements accordingly.
If you ever get the colored tile sequence wrong, the tiles reset automatically after about ten seconds. You don't need to leave the room or reload anything. Just wait and try again. Same goes for the loose floorboard — if you miss the click, walk away and come back, the plank is still there. After you get the flashlight, proceed through the right hallway again and click on the dark corner past the puzzle box. The flashlight reveals a hidden switch on the wall. Press it and a section of the floor drops down, revealing a ladder. Go down and you've cleared Chapter 3b Level 1. One last note: there is no trick answer or alternate path for this level. Some forums claim you need a second key from a later chapter, but that's wrong. Everything you need is contained within the current area. Just follow the steps in order and save often.
