1. Pick one home corner
Choose a bottom corner and grow your biggest tile there. Tiles in the bottom row only move when you merge them yourself, so a big number parked low stays put while the rest of the board churns above it.
2. Tap the tile where the result should live
The merged tile appears exactly where you tapped. With a pair of 5s next to your 6, tap the 5 that touches the 6: the new 6 lands beside the old one and the two are ready to join on the next turn.
3. Build a staircase
Line up falling numbers next to each other: 6, 5, 4, 3 along the bottom row. Each time the smallest step doubles up, it climbs one number and lines up with its neighbour. A clean staircase can turn into a chain of merges that ends at 9.
4. Clear small tiles high on the board
Pairs of 1s and 2s near the top are cheap to merge and refill from above, which mixes fresh numbers into the board without disturbing your corner. Use them when you need breathing room.
5. Wait for bigger groups when it is safe
Points are number × group size × 10, so three 4s are worth more than two. If a third matching tile sits one merge away, set it up first. Do not hold out when the board is nearly locked; a small move beats no move.
6. Watch the ceiling on new tiles
New tiles never go above two less than your top tile, and never above 6. Once you hold a 7, you will keep seeing 4s and 5s fall in. Plan spaces next to your mid-size tiles so those arrivals have something to join.
7. Keep one move in reserve
Before a merge, glance at what will be left. If your tap leaves only one other legal pair, think about the falling tiles: they could save the board or lock it. A spare pair you have not touched yet is your safety net.
8. Save Shuffles for the late game
A Shuffle early on mixes a board full of small numbers, which helps little. Late in the game, when tall numbers are stuck apart, a Shuffle can drop two 7s side by side. The board offers a Shuffle automatically before it locks, so you rarely need one by hand.
9. Use Undo for slips, not for fishing
Undo brings back the board before your last merge, but the tiles that fell in will be drawn again next time. Use it for a tap on the wrong side of a group. It will not reliably fetch a better random tile.
10. Let the hint teach you
Pause for six seconds and the largest group on the board glows. It is not always the best move, but comparing it with your own plan shows you groups you missed, especially bent shapes that wrap around a corner.
A sample run to 9
A typical climb: early merges of 1s and 2s build a 4 in the bottom left corner. Two 3s join beside it to make a second 4, and the pair of 4s becomes a 5. More 3s and 4s fall in and the staircase grows to 6, 5, 4. Two 6s meet for a 7, and a Shuffle late in the game lines up the 7s. Two more steps and the gold 9 lands with its crown, worth the 900-point bonus.
