Vita Mahjong Level 615 Guide: How to Clear Column Stacks

To beat Vita Mahjong Level 615 without spending coins on shuffles or undos, prioritize dismantling the dense central column stacks before clearing outer border tiles. The primary failure point on this board is matching easily accessible wing tiles too early. Doing so leaves buried suits trapped under multi-tiered columns with no remaining partners, causing unwinnable deadlocks.

Prioritizing Central Column Depth

In Mahjong solitaire rules, a tile is playable only when no tile rests on top of it and either its left or right side is completely unblocked. Level 615 places heavy vertical columns along the center axis, flanked by lower, wider wings. The top tile of each central stack traps several tiers underneath it.

When opening the board, follow this sequence:

Check Capstone Pairs: Scan the board for matching partners to the topmost tiles on the highest columns before touching perimeter pieces.
Clear Direct Blockers: Remove only the immediate side tiles that prevent access to the tall stacks.
Expose Buried Tiers: When presented with a choice between two valid pairs, match the pair that uncovers a deeper stack rather than clearing flat, single-layer tiles.
Track Remaining Stack Height: Always target the taller column when two stacks offer identical matching opportunities.

Managing Duplicate Suits

Standard Mahjong sets include four copies of each tile across the numeric suits (Dots, Bamboo, Characters), alongside sets for Winds, Dragons, and non-identical suit matches (Flowers and Seasons). Because you cannot see the faces of covered tiles, use the visibility of duplicate tiles to dictate your moves:

Tile Scenario	Recommended Action	Strategic Objective
4 Copies Visible	Match the two tiles that sit atop or block the deepest layers.	Frees locked columns while keeping the second pair available.
3 Copies Visible	Match the deepest column tile with one accessible outer tile.	Keeps one exterior tile open to pair with the fourth hidden copy.
2 Copies Visible (Both Open)	Leave both tiles on the board unless matching them frees a stack.	Preserves matching flexibility for newly uncovered pieces.
Flowers / Seasons	Clear immediately if either tile sits on a vertical stack.	Any Flower matches any Flower, instantly relieving column weight.

Using Outer Edge Tiles as Anchors

Easily accessible perimeter tiles function as safety anchors. If you match two open wing tiles together during the opening moves simply because they are highlighted, you exhaust that suit's utility.

When the third and fourth copies eventually appear deep inside the central columns, they may have no matching partners left on the board. Leave exposed border tiles in place until an interior tile of the same suit is uncovered.

Resolving Endgame Deadlocks

As the central columns thin out, the board shifts into a flatter, scattered layout. Deadlocks late in Level 615 typically happen when remaining tiles belong to conflicting suits that overlap horizontally.

Trace Blocked Paths Backward: Before making an endgame match, verify that removing those two tiles does not permanently wall off an odd number of remaining suit pieces.
Conserve Free Undos: If you uncover a dead end where no valid matches remain, use the Undo function immediately to reverse to the point where the buried piece was bypassed, rather than relying on an emergency shuffle.
