OktoGo is a mind game app made up of 18 short games built around quick arithmetic, counting and emoji matching. A few minutes a day is enough to exercise your focus and mental speed. Short rounds fit a coffee break, a commute or an evening at home.
ADVENTURE MAP
16 worlds and 315 levels, from Digit Village to Math Summit. Every level brings a different game. Collect 3 stars on each level and take on the tougher level at the end of every world.
18 GAMES
• Races: Quiz Race, Live Race, Ghost Race
• Speed and reflexes: Ship Voyage, Question Rain, Question Snake, Flying Bird, Bridge Run and a falling-blocks game
• Puzzles: Memory Cards, Answer Link, Tteok Pop
• Strategy: Lighthouse Defense, Diner
• Party: Bingo, Balloon Festival, K-pop Rhythm, Taekwondo Master
1,100+ QUESTIONS
Addition, subtraction, multiplication, division, missing numbers (? + 4 = 9) and mixed expressions with order of operations. Object counting and emoji matching (what does each animal eat, what hatches from an egg) add variety. With 8 difficulty steps, you start easy and move up as you get faster. A placement test sets your starting point.
SMART REPEAT
Questions you struggle with return at suitable intervals. The My Questions screen shows which ones you have mastered, and your profile shows your playing time and correct answers.
LEAGUES, DUELS AND LIVE RACE
Sign in with Google if you like: climb the weekly league, duel your friends, race everyone on the same 10 questions in the Daily Challenge and play real people at the same time in Live Race. You can also play as a guest without an account; signing in backs up your progress to the cloud.
CHARACTER CUSTOMIZATION
Use the coins you earn to customize the character Okto (hats, glasses, bow ties), pick up a 2x XP potion or a streak freeze, and unlock new ships.
