Strategies
Master basics first (Big Cup, Small Cup, Spike)
Foundation tricks enable all combos; take weeks-months to consistently land.
Grip variations for tricks
Standard grip for spikes; reverse grip for lunars; side grip for hooks.
String tension awareness
Loose string = easier for some tricks; tight = for grip-flips + spikes.
Sticky paint effect
Grip paint kendamas 'catch' tama better; enable tricks impossible on unpainted.
Freestyle building (music sync)
Choose music, plan trick sequences that hit beats — build routine iteratively.
Recovery from misses
One drop is fine; recover smoothly — visible frustration hurts artistic score.
