Chigai Tap
Read full descriptionHide full description
Chigai Tap is a simple brain-training puzzle game. Look carefully at a grid of characters and find the one character that is different from the rest. When you spot it, just tap it. The game uses letters, numbers, kana, kanji, and other look-alike characters. Even if you do not read Japanese, you can enjoy it as a visual puzzle about shape, balance, and tiny differences. Features: - Simple one-tap gameplay - Three difficulty levels: Easy, Normal, and Hard - Hint system that highlights the row or column containing the answer - Records for clear time, streaks, and total clears - Optional one-time Ad-Free purchase Great for short breaks, focus training, and quick visual puzzles.

Verdict
The clearest difference is in-app purchases: TETSUO at none against Chigai Tap's 1. TETSUO also leads on ads (none vs shown) and iOS requirement (7.1 vs 15.0). Chigai Tap's advantage is update cadence (every 3 days vs every 2 months). On price and device support there is nothing between them.
