KRUG
A quiet hex-merge puzzle. Adjacent tiles merge the instant their sum is a power of two — and one placement can cascade.
The rule
Place a tile on the hex board. If it sits next to a neighbour whose value sums with it to a power of two — 6 and 2, 8 and 8, 24 and 8 — the two merge on the spot. The merged tile then looks around again, absorbs the neighbour giving the largest power-of-two sum, and keeps going. That chain is the whole game: one well-placed tile can sweep half the board.
What's in it
- Campaign — 216 hand-authored levels across six themed worlds, each introducing exactly one new idea: seals, ice, vaults, rising junk, creeping blight.
- Endless — three difficulties, your own best score to beat.
- Daily run — the same seeded board for everyone, every day.
- Weekly league — a leaderboard that resets each week, with cloud save so your progress survives a new phone.
- Around 30 languages, and settings for sound, haptics and reduced motion.
