Logic Puzzles: Solvarium

Many puzzles. One app.

Solvarium holds 32 kinds of logic puzzle. Well-known ones like Nonogram, Slitherlink and Kakuro, and quieter favourites like Heyawake, Nurimisaki and Spiral Galaxies. Pick whatever you feel like today.

At first the board looks empty. Then one piece leads to the next, until it clicks.

EVERY DAY
Each kind of puzzle has a daily waiting for you, the same for everyone. Mondays start gentle, and by Sunday it gets tricky. Missed a day this week? Catch up on it with Sparks.

WHAT EACH PUZZLE COMES WITH
• A short intro on a real board
• A campaign in chapters, and endless boards in four difficulties
• A hint when you get stuck. It shows the next step and why it works.
• Your best times for each difficulty, and your mastery rank
• Every board is checked by a solver before it goes in

YOUR WEEK
Every puzzle you solve earns XP. In the weekly league you play in a small group. Finish near the top and you move up, from Pebble all the way to Diamond. If your profile is private, you play the friends league with a weekly goal instead. There are weekly quests too, and one streak across all puzzles. For the day you miss, there's a freeze.

WITH FRIENDS
• You all get the same daily, and you'll see who was quicker
• Challenge a friend with your board. They race your ghost, and then you can play a rematch.
• A weekly quest you can only finish together
• A shared streak that only holds if you both play

YOUR PROFILE
Your achievements and month trophies live here, and the Hall of fame shows what you've done so far. Playing earns you Sparks, and you spend them on making your profile look the way you like. Sparks can't be bought.

On first start you roll a name, or type your own if you're old enough. You don't have to sign up. If you like, back up your progress with Google, so it comes with you to a new phone.

The clock can stay off. There's a light and a dark mode, and large text if you need it.

Plus gives you no head start in the league or on the leaderboards.
