Oh I have seen this game before, @GPI, and I do like it !

Gold star and 💗 Favorited for turn-based and highly addictive play. Well done !

Alchemy Deluxe seems to have different rules.

In Mosaik you have a fixed set of stones. The stones on the playfield stay there and you can place new stones everywhere.

And thanks for the fav.

Oh you're right, @GPI ! They are similar but one major difference in Alchemy is if you get a full horizontal or vertical line, it takes it away clearing the board for future stones.

With yours you are expected to fill the entire board with a finite number of runestones.

Definitely different design. Nonetheless I really do like these sorts of brain games.

Here now, @GPI. Save a copy of the current board before the game ends. I wanted to show you how far I got and I didn't think the screen would vanish before the score appeared.

You can always copy the current screen to high-memory for later recall:

Save main screen: memcpy(0x8000,0x6000,0x2000)

Load that screen: memcpy(0x6000,0x8000,0x2000)

A little update.
Mouse-Cursor changed to a point over the playfield. Fixed a crash and the score is displayed with "," separated the numbers.

btw. my High-Score is 47,366,164 :)
