PutNumber is a fun puzzle game you can play at your own pace! Use your finger to slide the number blocks aligned below, and put them on any space on the board you'd like. You'll need to skillfully group and erase blocks, taking care to place them in a way that doesn't make the board fill up. ■ How to play ■ ・ Blocks are erased when you gather more blocks than the number written on the block. ・ Turn the blocks at the bottom around by tapping them. ・ Earn a higher score by erasing multiple numbers at once! (NUMBER LINK) ・ If you get a high score, you can use the C button to erase the selected numbers. First, try playing at the nice and slow pace of ENDLESS Mode. For people who want to enjoy the game for a shorter time or want a more intense play experience, we recommend TIMED Mode. Beginning with version 3, a new mode CURSOR Mode has been added. A completely free game app, PutNumber is popular for its reputation as a brain teaser that gives your mind a workout. Since you can play at your leisure, it's perfect for killing time whether commuting or simply waiting. It's super interesting, so please give it a try! ■ Production ■ AOTAKA STUDIO Game Planning and Programming: TOKUDA TAKASHI Game Graphic Design: TOKUDA AOI
