Logic Masters Deutschland e.V.

Feng the sixth had lost his bike,his newly bought bike. He had just found himself a girlfriend, whom he promised a ride in the sunset on a brand new bike, the one bike he bought for this special occasion, the one bike that took him months of saving, the one bike that was stolen in its first parking day. (references to previous story, which is impossible to shown for somebody posted the de-story version.)

It just happened that the designer of the lost bike parking-lot is a master of mystery art. Every tile was painted 1-9 and there were no repeated numbers in every row or column. The tiles were separated by gutters, forming a 9 tiles region which also had no repeated tile number. There was a bar for parking between two consecutive tile numbers. As for the parking, the designer also designed the rule.

Every bike took three tiles to park. It’s licence number should math the tile number, reading from left to right, up to down.

The bike can’t park above the bar.

One of the tires(ends) must be locked in front of a bar. The other tire (end) should not faced a bar. In other words, the bike shouldn’t be squeezed into two bars but it still needed one bar in front of one end to lock the bike.

On the day of the grand theft bicycle, all 9 bikes were stolen. All the bikes parked according to regulation. These bikes’ licence numbers all had a different starting digit, middle digit and ending digit. The three digits in one licence can’t share a same parity. The GTB thief on that day was a good one. Not only did he steal all the bikes, but also all the bars. He even wiped out some floor paint to cover his crime.

The following layout is what the CSI restored from that day. Some tile number is still there. The parking place was recovered with the help of the bike owners. Can you restore the crime scene and fond where Feng’s bike was?

If you actually learned Chinese, I highly recommend the origin wechat site (I really don’t think google translation would work),good luck.
