Think Tank: Word Game

NEW FEATURE - Leaderboard for daily challenge completion times!

Solve puzzles to collect fish! Think Tank is a relaxing, 100% free word game. Each puzzle is just three letters. Your goal is to make words by adding up to three more. Like, 'T N K' can become 'T h i N K' or 'T a N K'. It's so simple that you can play in your head - like chewing gum for your brain!

You can choose from casual (kid-friendly), standard, or challenge (for word nerds!). I hand-tiered 28,000+ words by difficulty to create these modes. You can hop into quick play for a minute or settle in and take on the campaign for an hour. Hatch eggs based on your streak in the daily challenge, or challenge a friend with pass-and-play versus mode. I've even included a night light mode so you can enjoy the glow and calming sounds of your favorite tank as you fall asleep.

Think Tank was designed to mellow quiet mornings and loud commutes. You can play in long lines, or at nap time.

If you love words or nature, I made this for you. Enjoy!
