- At least 4 of your chips are connected in any one direction (horizontal, vertical, or diagonal).
This puzzle can be solved using the following concepts. Practice using these concepts and improve your skills.
Each player takes turns to drop chips into one of the columns.
The game works as follows:
- A player gets full state of the board as input.
- The player chooses a column to drop their chip in (outputs a single integer in range [0,8])
- The chip falls in that column of the board and settles in the bottom most empty cell.
There are 9 columns, indices are [0,8].
0 => left most column.
8 => right most column.
The STEAL move for the second player: (optional)
- The second player can play "STEAL" for their first action.
- This action does not place a new chip on the board but will convert the opponent's one and only existing chip into the second player's own chip.
- This action is available only to the second player, and only for their first action.
- An example is illustrated below
First player placed a chip in
the middle column.
Second Player used "STEAL"
and converted the existing chip.
- The second player can output either the word
STEALor the integer -2for this action.
- Your program does not provide a command in the allotted time or one of the commands is unrecognized.
- It chooses a column which is already filled, or, not in range i.e. not in [0,8].
🐞 Debugging tips
- Append text with a preceding space after your output and that text will appear below your player's name. Longer messages will be shown in lines of 15 characters.
- Press the gear icon on the viewer to access extra display options.
- Use the keyboard to control the action: space to play/pause, arrows to step 1 frame at a time.
