All of Lasertank 101-150 GHS reached

[Liyifeng]

Hi all
To me, it is a very hard task and luckily I finally managed it all by myself. I should break all my mindsets, think out possible strategies and try to improve the score again and again.
Among the 50 levels, now I keep 17 GHSs and reached the other 33 GHSs(6 of them haven't been updated onto the official website).
Among the 17 GHSs, 7 of them are refreshed in late January and February in 2025.
I would like to share some experiences of solving levels I tried in 2025. In these levels, the GHS holders probably gave excellent solutions which are very efficient. I send my honor to these performances.
I don't mind you rebeat my GHSs after reading these informations, and I hope that you would like to write a comment here to share your experiences and opinions. I think that to SHARE is very important for the popularity of a game.
Although most of the levels have a GHS which won't be beaten forever, It is a very nice experience to try to reach (or luckily beat)them. It's a good training to do something more and more efficiently.

I felt totally at sea in this level, only to reach 34/42 in the first two days. And then! I found that I should push I14 block to I15, and push H15 mirror to J15.

#0126 225/136 by Iron(has been beaten)
There is an impressive solution in the south-west zone to push the blocks into water. although I have beaten the GHS but if not seen the former GHS, I couldn't imagine that I could push those blocks so efficiently.

The GHS solution is hiden well. The map looks so easy, so I was very confused before finding the right way.

#0138 117/117 by VVI(has been beaten)
There are so many strategies that can reach the flag. I had to compare these strategies day by day and made sure to bring D12M12 blocks into F1G1 water. The former GHS by VVI is skillful but he was probably a little careless to shoot G12.

#0141 186/141 by Iron(has been beaten)
The GHS probably shows good use of movable mirrors. You don't need to shoot P6P7 to death. I beat it by only 2 shots probably because of the holder's carelessness. In fact all the holders are bound to be careless time to time, to give oppotunities to other players.

#0143 202/205 by I&B(has been beaten)
The former GHS solution probably shows the top-class skill. I had tried it for 4 days before finding the right solution. I saved 18 lpb files to record the progress that I made. I share these 18 files to other players(see attachement) to show how a difficult GHS is gradually beaten. There are at least 4 main strategies: to push a block to O9 , or J9, or F9, and to use or not use B14 if you push a block to F9. The strategies have similar limits of shots so I had to compare them very carefully. My score stayed around 230 moves for long time and I felt very frustrated. But I built the confidence on the base of my habit. In fact as a teacher of math olympics, I am used to thinking a hard problem hour after hour, even day by day. I have the confidence that I can reach a score as long as one player once reached it.

#0144 70/126 by I&B(has been beaten)
It shows another example to use mirrors very efficiently. Thanks to the mirrors, there is a big cycle of laser to help you save moves.

#0150 939/384 by SzM(has been beaten)
I felt totally confused when I tried to reach this GHS for the first time, and the 2nd time, and the 3rd time. Recently I , for the 4th time, began to try it and succeeded. I admit that the difficulty is not less than #0143. I would like to share the key to reach or beat my new GHS: find another strategy. Don't fill D8 with a block. The new strategy seems impossible to reach GHS before careful thinking.

Have fun in hunting GHS

Why guys visited this passage for 40000+ times but left no words:-(
Does anyone know whether these are real persons...
By the way right now I have beaten the GHS of Lasertank_0179 being an inchworm... by Kheper. To me it is a masterpiece and Ihab's solution is very tough to reach. I kept 371 moves for years and today I return to this level and found the 369/287 moves solution. 5 minutes later, I found that 2 more shots can be saved.

Hi Yifeng, you've basically answered your own question! This forum has 65 members and many of them rarely check in here, if at all.

Most of those views are bots / crawlers. Some of these will be from Google, Baidu, Yandex, etc, updating their search engine databases. Others will be from hacking groups looking for useful info.
With the recent significant increase in AI (Artificial Intelligence) research & development, I suspect that many of those views will be sweeps of the web to gather training data.
Lastly, I got caught in a time-loop a while ago (I think) and 20,000 of those views are from me although it only felt like 1 visit to me!

Hah, insight is like that. I've done similar on levels where I was not able to find the last 2 moves (or shots) to match the GHS despite trying for an hour or two. Then I return to the level a few weeks later, find the GHS and then find another small saving a few minutes after that.
