Read full descriptionHide full description
Arrow Nova is a compact one-tap puzzle game about reading arrow paths and setting off the right chain reaction. Every board starts with arrows, blockers, and special pieces. Pick the best arrow, launch the chain, and clear the board with careful timing and planning. Levels are short enough for quick sessions, but each new layout asks you to think ahead. Features: - One-tap arrow chain puzzles. - Campaign levels with growing challenge. - Endless mode for longer runs. - Daily challenge with a fresh puzzle each day. - Coins, achievements, streaks, and unlockable board skins. - Hints, undo, and replay options. - Local progress with no account required. - Portrait layout designed for one-handed play. Plan the path, trigger the chain, and turn one tap into a full board clear.

Verdict
The clearest difference is ads: DD at none against Arrow Nova's shown. DD also leads on iOS requirement (13 vs 18.2). On price, update cadence, in-app purchases and device support there is nothing between them.
