9, 10, Black 9, 2.5, 69, %, and (Tic-Tac-Toe) chained onto [Infinity]
Level names and boss ability concepts:
The Devil's Backyard:
2.5 slaps its arms onto an opened tile to close it, while covering a 2x2 area as it moves on the board like 9, without changing the mines' positions. Sonar is banned.
The (im)Perfect Balance:
69 bounces around the screen just like 10, but with a bigger size and hitbox. Whenever its orbital mines hit your mouse (or the last spot you clicked on your mobile screen), you receive a penalty. For every time between 6 to 9 seconds, it'll throw mines at any closed tiles to open them by force, whether there's a mine or not. Click on those thrown mines in order to parry them. Shields give protection too. Anti-mines have a 6.9% chance to be found on the board.
The Devil's Casino:
% will try to confuse you by removing all numbers, and it'll display the chances of you getting a mine when you click on a closed tile (so it can be basically a full-on 50/50 if you're unlucky). Opening and flagging a tile will require two clicks/taps instead of one to prevent misclicks. Sonar cost is cut in half, and you only have one health. if you're playing on Boss Pursuit, there's only one boss instead of two.
The Devil's Tabletop:
(Tic-Tac-Toe) will force you to play a game of tic-tac-toe with it. You receive a penalty if you open a mine, lose in the tic-tac-toe, or not playing it at all. It'll keep starting new games until the board is clear. Health gauge and shields are applied like normal.
And i have no idea what mechanic to give for [Infinity]
The Devil's Knife Store:
Black 9 will be normal 9's phase 2. The board is bigger, and 9 moves significantly faster. It'll also turn the screen black for some time. The longer you take to finish, the longer the blackout will last. Effect is less effective if you're playing on casual or boss pursuit mode.
