Now tap the cog system on the left wall. Let’s solve this! Get it wrong and the spikes come out. Red cog in top left. Black cog in top right. Dismantle the green cog. Combine gold and blue. Place the combine gold and blue cog in the bottom part. The cogs mechanism will start working and you can exit.
Stage 4-4. 8421 is on every wall. Final door code is 8543.
Stage 4-5. Pick up the water bottle, matches, spanner and teddy. Dismantle the teddy to get 6 pieces. Dismantle the middle fluffy part of the teddy to get wool. Dismantle the left leg to get a green diamond.
Combine the cotton woll ball with the water bottle. Use the spanner on the left pipe to release the green smoke. To stop the smoke, use the cotton ball on the pipe to block it.
Use the matches to light the candle. Place the pipe over the candle. Put the green diamond on top of the pipe to show the code. The code is 389465.
Tap on the abacus on the wall near the door to enter the code. Quick tip on how Abacuses work: The top part is the 5’s, the bottom part is the 1’s. Each column has 10 allowable values. Just like normal numbers. So a 9 would be top down (for a 5) then 4 up from the bottom part. A 3 would be top up and 3 up from the bottom. Enter the code 389465 into the Abacus to exit the room.
