Show HN: Make a rectangle – a puzzle game
- kelukelugames 11y agoThe mods asked me to repost my puzzle game. Someone appreciates something I made. I want to cry. :)
- efeamadasun 11y agoHow does this game work? What am I supposed to be doing? Do you mind providing a short description? I could not manage to find one.
- kelukelugames 11y agoTry moving the pieces so they make a rectangle. :)
- pistoriusp 11y agoI think `make a rectangle!` is easier to understand than make a box :)
- kelukelugames 11y agoThanks! That might have confused people. I changed the title.
- scottcanoni 11y agoI assume the goal is to make a rectangle? Does it have to be a square?
- mistagiggles 11y agoRectangle, not possible to make a square. (Count the area and try and find integer width & height that fits)
- Someone 11y agoBut two squares is possible (8x8 with a negative 2x2 anywhere inside, including at the center)
- kelukelugames 11y agoYes, the goal is to make a rectangle. It cannot be one giant square as there are 60 (5 x 12) mini squares.
- chrisBob 11y agoIn safari I am able to rotate a pice by clicking, but I can only do it once for each piece. I am not sure if it is even still possible to complete it this way.
- kelukelugames 11y agoOh no. Thanks for the error report. I just re-prod the bug and will work on a fix. Sorry about that. It took me a while to get it working on Android and desktop. I need to get better at making things cross platform.
- petepete 11y agoSo I made a rectangle and nothing happened. Is it supposed to, or am I meant to simply bask in my quadrilateral glory?
- nkrisc 11y agoIs that not enough satisfaction!? What more do you want?
- kelukelugames 11y agoBask! Thanks for the suggestion. I should add a screenshot function or something. There are thousands of solutions so I couldn't figure out a good way to detect if the user was finished. Much to learn I have. :)
- brokentone 11y agoEdges with smoothing, and counting inside. If you only have 4 edges, then you win
- goorpyguy 11y agoYou'd probably have to check algorithmically. Starting from the top-left most piece, have they (reasonably fuzzily) covered the 6x10 grid proceeding down and right? If so, yay! You can also check for things like too much overlap, but checking if there is a piece covering each of the centers of the relative grid should be sufficient. My first solution: http://i.imgur.com/rV2Ueow.png http://i.imgur.com/rV2Ueow.png edit: It also was not clear up front that I could click to rotate/flip the pieces, until I did it by accident.
- Nadya 11y ago>edit: It also was not clear up front that I could click to rotate/flip the pieces, until I did it by accident. This explains why I couldn't solve it... I was feeling rather stupid seeing all the people solving it with 1,000's of solutions but I couldn't find one. Thanks! :P
- Marcus316 11y agoThis was always one of my favourite puzzle games growing up. I had a plastic copy of it that I would spend hours rearranging. For those who aren't familiar with this puzzle, the goal is to take the 12 pieces and make a 10x6 rectangle. The 12 pieces are known as Pentominos, and each one is a unique arrangement of 5 squares connected on the edges. There are more than 2000 different ways to arrange the pieces into a 10x60 rectangle. It's a lot of fun!
- kelukelugames 11y agoYes! Some Donald Knuth person even published an algorithm for it. :)
- ideaoverload 11y agoSame here. I kept notebook full of solutions I have found. My favourite trick was to use sets of 2 pieces placed next to each other that could be flipped without need to rearange other pieces. This way I could get 2 slightly different solutions in one shot.
- zem 11y agosame here! there are also lots of solutions for the 12x5 rectangle, and two for the 20x3
- kelukelugames 11y agoWow, people are solving it fast! Took me a few hours the first time. Granted I was 10. :)
- markbnj 11y agoGood start. Needs more snap :).
- zem 11y agofeedback: would be more satisfying if the pieces snapped to a grid. also are they not flippable? i couldn't find any way to do that.
- soral 11y agoCurrently the game is too complex, so it's not satisfying for an average user It might be a good idea to turn it into a game where it starts easy, gets harder, and you can share the level you achieved and brag about it (like 1 2 3 4 5 6 7, the level could be stored in localStorage so a user can continue fresh from that same level later on, with a different random pieceset) Edit: Just checked the code, impressive :) - I assumed the game and pieces were randomly generated
