The series

Five apps, one idea

Whether you are beginning, returning to Japanese, or building speed, each game keeps English and Japanese in the same play session. The challenge changes, but both languages stay together.

Drive Go Go app icon

Drive Go Go

Learn words. Drive further. Have fun.

A gentle driving-and-spelling game for beginning learners. A word appears with one letter missing — collect the right letter from the road while you drive.

The calmest game in the series, and the best starting point. There is no timer and no game over: the run just keeps going, so anyone still sounding words out has time to think.

How to play

  1. 1Hold the device in landscape, flat like a tray, and tilt gently to move between three lanes.
  2. 2The banner at the top shows a word with one letter missing, plus an emoji hint for what it means.
  3. 3Collect the correct letter from the road. Pick up the wrong one and nothing bad happens — keep driving and try again.
  4. 4Drag the gear shifter for LOW, MID, or HIGH speed. Cones, boxes and flowers slow you down, so steer around them.
  5. 5Spell words in a row to build a combo.

What's inside

  • 180 English–hiragana word pairs, shown together after each correct answer
  • Pick English or Japanese (hiragana) under Grown-ups
  • Short words for beginning learners — 2 to 4 letters, or 2 to 4 kana
  • Emoji hints, so meaning stays clear even when the word is still new
  • Cars with their own powers: Magnet, Turbo, Bouncy, Hopper
  • Grown-ups can also set the road theme, metres or miles, and sound
  • No timer, no game over, no ads, no third-party analytics
  • Free to play. Optional one-time Drive Go Go Pro unlock ($2.99) behind a grown-up gate

Bilingual Samurai

Slice the spelling.

A fast slicing game. A word appears, letter and kana tiles fly up from below, and you slice them in the right order before time runs out.

The reflex game of the series. Reading fast is a skill of its own, and this is where it gets built — under a clock, with decoys mixed in, in whichever direction you choose.
