Last Tile Finder[]

Missing the last 10 tiles or less in a location? This Tool will help you find them!
The Last Tile Finder (LTF) is a reusable tool that helps you find the last 1-10 tiles in a mine.
It works anywhere except repeatable mines, but only when there are 10 or fewer tiles remaining.

Buying the LTF[]

The LTF is sold in the 'Extras' tab of the shop.
Once bought, it's available permanently (but needs time to recharge after use).

Cost
level 30	250
level 50	50,000

Using the LTF[]

Whenever you are in a non-repeatable mine, the LTF button is visible in the corner of the screen.

On the mobile version the button is in the bottom-right corner:
On the computer version it can be found in the top-left corner:

Clicking the button opens a dialog which will either tell you there are too many tiles left, display the recharge options, or let you activate the LTF.

Once activated, a golden trail will run from Diggy towards the first detected tile, or a door that leads to tiles. When you go through a door (or if you lose sight of the trail), click the LTF button again to show the trail again. The LTF will stay active in that mine until it is cleared. Recharging takes 24 hours from the moment the LTF is activated, and it can be active in multiple mines at once - there's no need to rush to clear them.

Recharge options: This dialog shows the time remaining to recharge normally. To recharge instantly, you can either pay 30 or watch an ad (limit one ad per day, ads refresh at midnight UTC).

LTF Troubleshooting[]

Some maps, especially those with looped paths, can confuse the LTF. If it's sending you in circles from door to door, the workaround is to visit each screen of the mine, running the LTF each time - if it leads to a door ignore it and go to the next screen. Eventually you'll be on a screen where it can lead you to tiles. To make sure you visit all the screens, check the wiki's maps for that mine.

If the last tile is somewhere inaccessible, the LTF might not work, or might direct you straight through the obstacle. Try to clear a path by moving stones, pulling levers etc.

Passive Effects[]

How do Passive Effects Work[]

There are currently two types of the Passive Effects

An Experience Passive Effect. Double XP.
An Energetic Passive Effect. Energy back.

If the Experience Passive Effect is purchased you get a chance to receive double experience from the tiles that you are digging. The chance increases with each level. When you enter a mine first time the percentage of tiles will be set to double XP at random. When active this is indicated with a yellow "Bonus" special effect in the mine. In effect leveling you up faster.

If the Energetic Passive Effect is purchased you have a chance to get back the energy from the tile that you have just dug out. The chance to get the energy back increases with each level. When you enter a mine first time the percentage of tiles will be set to give back energy at random. In effect it improves your energy production by the percentage in the long run. When active this is indicated with a green "Bonus" special effect in the mine.
