Layer the colors, let them flow, and gather ten to watch them bloom. Kasane is a calm puzzle about stacking colored tiles on a hexagon board. HOW TO PLAY - Place the stack in your hand on any empty cell - When neighboring stacks share a top color, the tiles flow together - Gather 10 of one color and they drift away like petals - Clear again as colors regroup to build a Kasane chain for bigger scores - Soft arrows show where colors will go before you place MODES - Score: play until the board fills and chase your best - Today's Seed: a fresh 30-move deal every day, once a day KASANE COLORS Eight palettes inspired by the layered robes of the Heian court: Plum, Willow, Cherry, Kerria, Maple, Chrysanthemum, Under the Snow and Pine. A Japanese pattern mode lets you tell colors apart by pattern, too. MADE FOR QUIET PLAY - Play offline - No timers. Leave anytime and pick up where you left off - Layouts for iPhone, iPhone Duo and iPad - Records stay on your device. No account needed

Verdict
The clearest difference is in-app purchases: トンツー at none against Kasane's 1. トンツー also leads on update cadence (every 6 days vs every 3 weeks) and iOS requirement (15.0 vs 17.0). Kasane's advantage is ads (none vs shown). On price and device support there is nothing between them.
