Grok Gems

An original alien match-3 game. Swap two neighbouring gems to line up three or more of the same kind. The six gem aliens are Zap, Bloop, Glim, Squidge, Fizz and Nubb. Matches clear, gems above fall into the gaps, and new ones drop in, which can set off cascades worth more points (up to ×5).

Special gems

4 in a row: makes a Line gem (striped). It clears its whole row or column.
L or T shape: makes a Bomb gem (ringed). It clears a 3×3 area.
5 in a row: makes a Nova (rainbow orb). Swap it with any gem to clear every gem of that colour.
Swapping two specials together gives a bigger blast:
- Line + Line clears a cross.
- Line + Bomb clears three rows and three columns.
- Bomb + Bomb clears a 5×5 area.
- Nova + special turns every gem of that colour into that special.
- Nova + Nova clears the whole board.

50 levels in five worlds: Crystal Shallows, Jelly Moons, Frost Ring, Pod Nebula and Grok Core. The early levels are gentle and the later ones mix goals.

Jelly: clear gems on top of the pink jelly. Double jelly needs two hits.
Ice: break the ice blocks with matches next to them or with special blasts. Thicker ice takes 2 hits, and crystal rocks take 3.
Pods: bring the little ships down to the bottom of the board.
Score: reach the target score before you run out of moves.
Timed rush: score as much as you can before the clock runs out.

Every level has a move limit or a timer. Moves you don't use are worth 150 points each, and leftover seconds are worth 30 each. Each level is rated 1–3 stars. Replay a level to improve your best score and stars. The board shuffles itself if no moves are left.

Boosters:

Hammer: smashes one gem or ice block.
Shuffle: mixes up the board.
+5 moves (or +10 seconds on timed levels).

You get one free booster every fifth level you clear, and a Hammer for each new 3-star rating.

Endless: 30 moves on a full board. Every special gem you make adds a move. Your best Endless score counts towards your total.

Daily Challenge: one seeded level that's the same for everyone that day. You get one try and boosters are off. You still get half the points if you lose.

Score: your total is the best score of every level times the difficulty bonus (Normal ×1.25, Hard ×1.5), plus your Endless best and a 15000 bonus for clearing all 50 levels. Difficulty also changes the moves you get: Easy +5, Hard −4. Log off to post your score. The game autosaves with no undo, and every score is replay-checked on the server.
