About
Grip your iPhone like the hilt of a katana and draw it from your hip in one motion.
Sayabashiri ("the blade leaving the scabbard") is an iai sword-drawing game that measures your slash with the iPhone's motion sensors and scores it.
HOW TO PLAY
1. Tap "Start"
2. During the 5-4-3-2 countdown, hold the phone like a sword hilt at your left hip
3. Hold still on 1
4. When the phone vibrates and "Draw!" appears, draw, slash and stop
Draw before the signal and it is a false start. Patience is part of iai.
SCORED OUT OF 100
- Edge alignment (40): does the blade's axis stay true while you swing?
- Speed (30): how sharp is the draw? (capped, so swinging harder does not help)
- Stop (20): does the blade stop cleanly at the end?
- Arc (10): is the rotation the size of a real drawing cut?
Reach the pass mark and the target is cut along the angle of your slash. Fall short and the blade stops halfway.
THREE TARGETS
- Straw mat / makiwara (pass: 60)
- Bamboo (pass: 75)
- Armor and helmet (pass: 90)
Straw mat and bamboo can be challenged any number of times. For the armor, watch an ad to get 3 attempts, or unlock it with an in-app purchase that also removes all ads.
PLAY SAFELY
- Grip the phone firmly and use a wrist strap if you have one
- Make sure no people, objects or walls are nearby before you swing
- You do not need to swing with full force. Edge alignment and the stop are the keys to a high score
