A number puzzle where 9 + 9 scores nothing

Hi, I'm Antti, a solo developer in Finland, and this is Prim3 Hunt: Core, a number puzzle for Android.

The rules fit in three lines:

• Chain two or more adjacent tiles.
• Equal numbers add up, different numbers subtract, and the result lands on the last tile.
• Only the target prime scores.

So 9 + 9 makes 18 and scores nothing. Five moves without hitting the target and the run is over. A short chain hits the prime now; a longer one scores more: 4 tiles score 2x, 5 tiles score 3x.

What's in it

• Initiation lessons that teach the rules one step at a time
• Classic, Time Limit, Move Limit and Endless (with Prim3+)
• A Daily Challenge with a new rule every day, the same for everyone
• 14 languages, cloud save, and a retro CRT look

It is free to play, with one-time unlocks for more, and there are no forced ads: an ad plays only when you choose one for a reward.

Prim3 Hunt: Core launches on Google Play in November. If it looks like your kind of puzzle, pre-registering is the best way to help a one-person studio:
