Sena's Prism Cascade guide
Drop vertical trios of gems into a well six cells wide and thirteen tall, and line up three or more of a colour horizontally, vertically or diagonally. The trio never rotates; you can only cycle the order of its colours, so choosing which gem sits at the bottom is the heart of every move. Nine stages through Sena's crystal glasshouse, from Dawn to Starlight, each add one new goal, and clearing Noon opens the Endless Crystal mode.

How to play
- Choose a stage. Nothing falls until you first move or cycle, so take your time with the opening.
- Move with the side buttons, ←→ or A/D, and cycle the colour order with the cycle button, ↑/W or a tap on the well. Each cycle brings the top colour down to the bottom.
- Tap the drop button, press Space or Enter, or swipe down to drop at once. Holding the drop button or ↓/S makes the trio fall faster only while held. Gamepad: D-pad, A cycles, B drops.
- Three or more of one colour in a line disappear and the gems above settle. If settling gems match again, the chain continues; each gem scores 10 points times the chain step.
- Every stage has a gem target, and some add a chain count or a diagonal-clear goal. Meeting all goals clears the stage and adds 400 points.
- The run ends if the spot where new trios appear is blocked, or if a trio comes to rest sticking out above the well.
Strategy tips
- New trios appear at the top of the fourth column from the left. If that column fills first the run ends even with other columns empty, so keep the centre low.
- Check the gold outlines before dropping. They mark gems that would clear right now, and the forecast under Target shows the expected clear count and chain. The Preview button turns this off. The next trio's colour order is also shown, so plan two drops at a time.
- In Morning Dew and Chain Garden, which have chain goals, stack a matching colour one layer higher so it drops into a match after the gems below clear. Every drop that reaches a chain of two or more counts once.
- Diagonal House needs nine gems cleared on diagonals. Building columns of different heights like a staircase makes diagonal lines much easier.
- Crystal Bed starts on three rows of crystals laid so none match. Drop fitting colours into the gaps and dig through the bed layer by layer.
Common questions
How do the nine stages differ?
Dawn and Morning Dew use three colours; Noon, Diagonal House and Crystal Bed use four; Afternoon, Chain Garden and Dusk use five; Starlight uses six. Gem targets rise from 24 to 66, and the fall speed increases stage by stage.
When does Endless Crystal open, and how does it play?
It opens once you clear Noon (stage 3). It is a score chase with no target: every 30 gems cleared raises the level and the fall speed, and the gem set grows from four to five and then six colours. You earn a star at 3,000, 9,000 and 20,000 points.
I find it hard to tell gems apart by colour.
Every gem also carries its own symbol, so you can think of it as matching three of the same symbol. Matches are always between gems with the same colour and symbol.
Can I continue after stopping?
Pausing or leaving the window saves the well, and reopening restores your last board in a paused state. Esc or P also pauses.
