Pour jellies from tube to tube and gather each color together. Fill a tube with four of the same color and it's done. That's the whole rule. ■ Some colors have to be made From level 21 a dashed tube appears. This one accepts colors that don't match. Put pink and lemon in, tap the tube, and you get orange. Put all three primaries in and you get white. Missing a color? Make it. ■ 120 levels, six worlds Every 20 levels the whole screen changes color: cream, sunset, ice, plum, ocean, electric. Past the last level there is an ending. This isn't a game that runs forever. ■ No need to hurry No timer. No lives, no hearts, no waiting. A wrong move is just an undo away, and when you're stuck there are hints and an extra tube. ■ Jelly collection Three faces for every color, opening one by one as you complete tubes of that color. Every ten levels you also receive a bottle. 48 slots in all: 36 jelly faces and 12 bottles. ■ Daily puzzle One a day. Everyone in the world solves the same one that day. ■ About this app - No sign-up, no login - Your progress stays on your device and is never sent anywhere - The game works without an internet connection - 한국어 · English · 日本語 · Español · 简体中文 · 繁體中文 · Français · Deutsch · Português · Italiano · Русский · Türkçe · Bahasa Indonesia · Tiếng Việt ■ No ads at all There's no advertising in this app. No banners, nothing that interrupts you.

About

Mastermind

Features
Read full description

Bulls and Cows is a single-player logic game: guess the secret number before time runs out. Digits never repeat. After each guess you get hints. The app uses the Spanish terms Fija and Pica in every language: • Fija (bull): the digit is in the secret number and in the correct position. • Pica (cow): the digit is in the number, but in the wrong position. Choose one of four levels: • Easy: 3 digits, 3 minutes. • Medium: 4 digits, 3 minutes. • Hard: 5 digits, 4 minutes. • Extreme: 6 digits, 5 minutes. There is no attempt limit: you win by cracking the code and lose only when the timer hits zero. Unlock 8 achievements for speed, precision, and difficulty. Progress is stored on your device. The app includes in-game rules, needs no account, and does not connect to our own servers. Free, with no ads and no in-app purchases. Questions? Write to hello@kurubatech.com.
