Guess the state. The question shows the surrounding states. Question: Oregon Idaho Answer: Washington This app will give you a better understanding of the state's location. It is especially for those who can indicate which state is on the map when told the name of a state or who can say what state it is when pointed to on the map. Compared to simple problems, guessing from the surrounding states requires a solid understanding of their locations. It requires new thinking. It is assumed that you will not look at the choices until you find it. Challenge yourself to eliminate the candidates correctly by looking at the states in question. Reading out the questions makes for a fun game recommended for large groups. Utah, Colorado, Arizona, and New Mexico are touching at one point. All combinations are in contact with each other. Colorado and Arizona touch. Utah and New Mexico touch.
Hangul Builder

Want to read the names of your favorite K-pop artists, follow along with lyrics, or make sense of signs and menus in Korea? It all starts with Hangul, the Korean alphabet. Hangul Builder is a Korean alphabet app for beginners. It teaches Hangul the way it was designed: as a system of consonant and vowel parts that fit together into syllable blocks. Instead of memorizing each syllable block as its own shape, you learn the parts and how they combine. BUILD SYLLABLES WITH YOUR OWN HANDS Drag consonant and vowel blocks together and watch them snap into a syllable. Seeing how a syllable is put together helps you understand it rather than rely on rote memorization. PRONUNCIATION TIPS FOR ENGLISH SPEAKERS Each consonant and vowel comes with explanations written for English speakers, comparing Korean sounds with familiar English ones. Tap to hear Korean pronunciation (text-to-speech) for letters and syllables. THE LOGIC BEHIND THE VOWELS Korean vowels are built from three simple strokes: heaven, earth, and human (Cheonjiin). Learn the idea behind them, and the vowels start to make sense as a system. HANDWRITING PRACTICE WITH FEEDBACK Learn to write Korean: trace each letter with your finger and get automatic feedback on stroke order and balance. TYPING STUDIO Use the Hangul you've learned and practice typing it yourself on your phone or PC. A keyboard setup guide shows you how to add a Korean keyboard to your phone. A STEP-BY-STEP 7-DAY PATH Work through the basic Hangul chart, one row at a time: - Day 1: the 10 basic vowels and the ㄱ row - Days 2-7: the remaining consonant rows The 7-day path covers all 140 basic syllables (14 consonants x 10 vowels). KEEP GOING AFTER DAY 7 - Final consonants (batchim), including double finals - Tense consonants and complex vowels - Travel Hangul: practice reading signs and menus - Kumitate Words: build 140 practical words from the letters you learned - Connect Square: practice typing in 5 parts: Review, Search, Chat, Introduce yourself and Order STUDY YOUR WAY - Spaced repetition review focused on the letters you miss - A collection that grows as you learn new letters - Progress tracking, streaks, and badges - Offline learning (Premium) - Study with KumiTora, the tiger mascot FREE TO START Start for free, then unlock more with Premium: - Premium Monthly (auto-renewing subscription) - Premium (One-Time Purchase) SUBSCRIPTION INFORMATION - Payment is charged to your Apple Account at confirmation of purchase. - Premium Monthly renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
