Beat the computer with four pieces in a row!

Instructions to play connect four

The rules are simple: You play against the computer and you both have 21 discs (or markers) each. Depending on what level you selected, either you starts (with red discs) or the computer starts (with yellow discs). Click on the column you want your disc to fall down into. The disc falls to the lowest empty slot in that column. Then you wait for the computer to put it's disc. When the computer is finished, you can add your next disc.

To win in connect 4

The first to get four of their pieces in a straight line wins. A line can be horizontal, vertical or diagonal. You have to beat the computer to finish the round. If it's a tie (the whole game board is filled with discs) you have to try again.

Considerations in the game

On the more difficult levels, your computer often has to think for a long time to find a really good place for its disc. If you have a tired computer, this can take several minutes and during this period of time a pulsating spinning circle in the middle of the board will be shown.

Calculation of knowledge points

Each completed game level gives 1 knowledge point in Connect 4. The maximum number of points (14 knowledge points) is achieved when you pass all 14 levels. You'll get a bronze medal when you complete a level 2 times and a silver medal after 5 completed rounds. A gold medal will be received after 10 completed rounds. In Connect 4, the maximum number of collectable gold medals is 14. You only earn knowledge points for levels that has not been cleared before. A cleared level has a green background above. Even when you have completed a level, you can continue practicing at that level, but it gives you no more knowledge points.

there's no need for AI to think after I made 3 in a row with a possibility of a 4th. level 13: AI could still go for another 6 moves in a lost position, but decided to lose directly. It was actually lost another 6 moves before.

It is impossible to win after 3 moves, how!!!!!

I like the game, but the computer could definitely be stronger. I played five games with it, and blundered an average of once every 12.5 moves. Also, it allowed a win on the second row a lot, and it blundered away a loss on move 2 in 4/5 of the games.

The first game I played was the exceptionally hard level and won on my first try. I'd rate 5 if there was harder modes.

anon: Thanks for the feedback. I've corrected this now so it's no longer possible to make a move on a full column.

anon

I placed in the centre column when it was full, and it took my turn away. I also lost the game.

This bot is pretty sub-optimal, it should be impossible for me to win on the hardest difficulty if the bot goes first but it gives me 2nd row win incredibly early.

lvl 14 in 14 moves is the most perfect round possible for me

This game is really harder for me but I think ? that everyone can use their brains ? to solve it??.

I just beat levels 11 and 12, 11 was way harder to beat, it took me twice as many moves to beat level 11 than it did level 12.

I just beat level 10 is it harder than level 11 I don't know

plus

24 April 2018 21:51

In my opinion level 10 is somewhat harder than levels 11 and 12.

kieren

19 April 2018 16:20

it's real fun also level 11 is a harder than level 12

moujik

One of the better AIs out there. Still I win every time.. level 11 is a bit harder than 12, so you need to concentrate..

Level 12 is easy to beat. The algorithm for the computer needs changed to make the game more challenging.

I finally got a gold medal on level 10! I studied how I won the first time, and found out the computer always seems to make the same guess and same mistake on a certain part of the game. I caught it! After finding that, it was easy to win over and over since the computer doesn't read it, and it keeps making the same wrong move. it doesn't read my move as a threat. I don't want to mention my actual moves since I know they will update the software hehe ;)

27 January 2017 09:28

It is possible to win on level 10 also (but it's hard), the computer does not play 100% perfect, but close to it.

Vancouver: You loose unless you beat the computer. That's the rule here. :)

Why does it say i lose when it's a draw? It doesn't matter who starts first, if it's a draw, it says i lose...

math

6 June 2016 08:24

it is impossible to win if you allow the computer to go first on level 10. in order to win on level 9 you must place your piece in the center on the first move then proceed to play a perfect game.

what does " someone had a problem...... " mean ?

Hmm

What does 'Someone had Problem with (ex. level 7)' mean?

Heh, perhaps it was the crumminess of the algorithm then that caused my bot trouble, since mine was expecting the opponent to make perfect moves.

Anyways, if any of you is working on a bot of your own, this is what I ended up with: minimax with a depth of 9-ish, heuristics to take even/odd row threats into account and you should be all set. With the use of bitboards and some clever hash maps, you will always make your move in less than 2 seconds on a regular desktop computer.

It's not that haard to win if you put 2nd. And I don't even now what an algorithm is :p

This videogame is really useful to train the brain! Right-hand good!

Phvli

9 October 2014 04:16

Hmm actually nevermind, I found the original algorithm. It was my heuristic that wasn't up to the task. Adding odd/even row threats to mine was sufficient, and now I have yet to find an online solution that can beat mine.

Anyway, yours is the toughest opponent. Kudos!
