Recently, I made Battle CP!
It's pretty much Battleship meets competitive programming. My friends and I have had a great time playing it, and it's a really fun way to practice with others.
We even held a tournament at our college which was a great success. Huge thanks to the Coders' Club IIIT Kottayam for hosting the tournament, helping with playtesting, and providing valuable feedback!
Here is a basic overview of the game:
- Lobby: Create or join a lobby and invite a friend.
- Placement Phase: Each player places a fleet (standard 5 ships) on a 10×10 grid.
- Combat Phase: Players take turns firing at coordinates to try and sink ships.
- Heat Mechanic: Each shot increases your heat. When heat reaches the overheat threshold, your weapons lock!
- Unlocking Weapons: Solve a Codeforces problem shown in the Problem Panel to instantly unlock your weapons.
- Vetoes: You have a small number of limited vetoes that let you bypass a lock. However, you will get punished with a time penalty before receiving a new problem.
Win Conditions: - Sink all of your opponent's ships. - If time runs out, the player with the most ships sunk wins (if those are equal, the tiebreaker is the number of hits). - If still equal, you enter Sudden Death (first hit wins!).
You can read more detailed rules on the website's homepage.
I've done my best to make the game fun, problem-solving focused, and super customizable. I'd love some feedback from the community and hope you guys have a great time playing it!
