PutNumber is a fun and addictive puzzle game available on iPhone. This game allows you to play at your own pace, making it perfect for both short bursts of entertainment and longer gaming sessions. The objective of the game is to slide number blocks onto the board and skillfully group and erase them without filling up the board.

To play, you use your finger to slide the number blocks aligned below and place them on any space on the board. Blocks are erased when you gather more blocks than the number written on the block. You can also turn the blocks at the bottom around by tapping them. The game rewards you with a higher score for erasing multiple numbers at once.

PutNumber offers three different game modes. The first is the "ENDLESS Mode," which allows you to play at a nice and slow pace. For those who prefer a more intense experience, there is the "TIMED Mode." Additionally, a new mode called "CURSOR Mode" has been added in the latest version.

Developed by TAKASHI TOKUDA of AOTAKA STUDIO, PutNumber is a completely free game app that has gained popularity for its reputation as a brain teaser. It provides a great workout for your mind and is perfect for killing time during your commute or while waiting. Give it a try and see if you can master the challenge of PutNumber!
