[MEGAGRID MOD] Isaac's Minesweeper
Core controls
CheckLeft-click places or removes a flag on a tile. To reveal a tile, simply walk onto it. Step on a mine and the round ends in failure, so flag suspected mines before you move through an area. If you are unsure about any tile type or mode rule, the game's built-in guide explains all of them.
- Left-click on a tile to place a flag; left-click again to remove it.
- Walk onto a tile to reveal it.
- Never step on a tile you suspect holds a mine; flag it first.
- Open the built-in guide for a full breakdown of every tile and mode.
Reading your stats mid-round
SummaryTwo stats appear while you play. Flag Rate and Tile Rate each track a specific part of your performance, so it helps to know what goes into them and what does not.
- FR (Flag Rate) correct flags placed per second
- TR (Tile Rate) tiles revealed per second by direct steps only
- Blank/zero tile chains these reveal neighbours automatically but do not add to TR
- Completion the share of special flags you currently own
- Flag chance TR divided by time multiplied by player count, viewable by typing /console in chat after a win
Solo badges and time targets
StepThe timed badges all require finishing a Normal Mode round at 16% mines solo within the target time. The Sub 50 badge exists but does not count toward your Completion percentage.
- Sub 100 finish a Normal Mode round at 16% mines in under 100 seconds.
- Sub 90 the same conditions in under 90 seconds.
- Sub 80 and Sub 70 each step rewards a numbered flag.
- Sub 60 is a further step down.
- Sub 50 does not add to your Completion percentage, unlike every other timed badge.
Special mode badges
TipsBeyond Normal Mode, completing each special mode solo unlocks a unique flag badge. The Random Mode badge accepts any one of six variants: random, largerandom, hugerandom, massiverandom, colossalrandom, or size random. Size Star Mode is noted as particularly hard with a lot of guessing involved. The Minesweeper God badge requires you to hold the Minesweeper God rank for at least five seconds — it is a separate rank from Godly, so do not confuse the two.
- Complete any one of the six random variants to earn the Random Mode badge.
- Size Star Mode involves significant guessing.
- Minesweeper God rank must be held for at least five continuous seconds to trigger the badge.
- Godly rank and Minesweeper God rank are different — only the latter counts for that badge.
- Algebra, Bot, Inverse, Chess, Control, Minepower, Size, Size X, Size Cross, and Xs and Crosses modes each have their own solo badge with a unique flag reward.
Multiplayer mode flags vs. solo badges
TableThe game splits its rewards into two systems. Badges are earned by winning the required mode alone. Mode/mod flags are earned in multiplayer when you clear enough tiles.
| Badges | earned by winning the required mode alone |
| Mode/mod flags | earned in multiplayer when you clear enough tiles |
| Tile threshold | all tiles cleared by players, divided by player count, divided by 2 |
| Flag chance check | type /console in chat after a win to see your numbers |
| Room size | up to five players can share a room |
Grinding Infinite Mode tiles
StepInfinite Mode tracks your cumulative directly-stepped tiles. Tiles revealed by blank-tile chains do not count toward the total. The three milestones each unlock a flag badge.
- Reach 1,000 direct-step tiles to earn the loop flag badge.
- Reach 5,000 direct-step tiles to earn the universe flag badge.
- Reach 10,000 direct-step tiles to earn the spacediamond flag badge.
- Chain-revealed tiles from blank steps are not counted only direct steps matter.
Glossary
Glossary- FR (Flag Rate)
- The number of correctly placed flags per second, shown as a live stat during a round.
- TR (Tile Rate)
- The number of tiles you reveal per second by directly stepping on them; tiles uncovered by blank-tile chains are excluded.
- Completion
- The percentage of special flags you own out of all available ones; the Sub 50 badge does not contribute to this number.
- Mode flag
- A special flag reward tied to a specific mode that can only be earned through multiplayer, as opposed to a badge which requires solo play.
- Blank/zero tile
- A tile with no adjacent mines; stepping on it automatically reveals surrounding tiles, though those extra reveals do not raise your TR.
- Minesweeper God rank
- A specific in-game rank, separate from the Godly rank, that must be held for at least five seconds to unlock its badge.
Common questions
FAQDo I need other players to earn badges?
No. Every badge in the game can be earned playing solo. Multiplayer is only required when you want to earn mode or mod flags, which are a separate reward system from badges.
Does the Sub 50 badge count toward my Completion percentage?
It does not. You can earn the Sub 50 badge, but it does not count toward Completion.
How do I check my flag chances after a round?
After winning a round, type /console in the chat. This displays your flag chance numbers.
Which random mode variant do I need to complete for the Random Mode badge?
Any one of the six qualifies: random, largerandom, hugerandom, massiverandom, colossalrandom, or size random. Finish any single one of them solo and the badge unlocks.
Why is my TR low even when I clear a lot of tiles?
TR only counts tiles you step on directly. When you step on a blank or zero tile and it chains open a cluster of neighbours, none of those extra revealed tiles add to your TR.
