Triangulation Slot Review

Provider	Microgaming

Triangulation is a Microgaming slot released in 2012 that ditches the standard reel format entirely. Instead of spinning symbols on columns, you get a billiard-rack-shaped grid containing 16 triangles in 7 different colours: black, violet, blue, deep red, green, yellow, and red. It plays on cluster-pay mechanics rather than fixed paylines - you need 4 or more adjacent matching triangles to register a win. The RTP sits at 96.7% with medium volatility, and bets run from £0.10 to £50 per spin.

If you like Moonshine or Cash Crazy from Microgaming, this is a different animal altogether - sharper visually and more puzzle-like in how winning combinations build and cascade. It suits players who want something outside the standard 5x3 grid with 20 paylines.

How Triangulation Works

The 16-triangle grid is arranged in a triangular frame - picture a snooker ball rack. Each position holds one of the 7 coloured triangles. On every spin, new triangles drop into place and you need clusters of 4 or more identically coloured adjacent triangles to form a paying combination. The more triangles you chain together, the bigger the payout multiplier.

When a winning cluster is paid out, those triangles are removed and replaced by fresh ones cascading down into the empty spaces. This cascade mechanic means a single spin can produce multiple consecutive wins without any additional cost - a chain of combinations builds within one play. At £50 per spin maximum bet, the cascade potential is where the real earning power lives.

The payout schedule runs from black triangles at the bottom (0.1x multiplier) up through violet, blue, deep red, green, and yellow, with the wild red triangle sitting at the top of the pay table at 10x your bet. Achieving a large cluster of high-value coloured triangles alongside wild substitutions is the core goal of every spin.

Wild and Red Triangle

The red triangle acts as the wild symbol. It substitutes for all other triangle colours and can form its own winning clusters independently. A pure cluster of red wilds pays up to 10x your total bet - the highest fixed multiplier in the game. Beyond completing combinations, reds that appear in any mixed cluster boost the value of that group, making them the single most important symbol to land.

There are no scatter wilds, sticky wilds, or expanding wilds here. The red triangle works cleanly as a standard wild - it lands, it substitutes, and the cascade mechanic does the rest. Simple, but the 10x ceiling on wild clusters is competitive for a medium-volatility game.

Swap Out Bonus

Three or more blue bonus triangles appearing in the grid after all cascade wins have been paid triggers the Swap Out Bonus. This is Triangulation's only dedicated bonus feature.

In the Swap Out Bonus you get to select 3 triangles from the grid and convert each one into a wild red triangle. With 3 wilds placed strategically, you can often create or extend a high-value cluster, and any wins from those converted wilds are then paid out at normal rates before the grid refreshes. The bonus does not involve free spins or a multiplier applied to the total payout - it is purely a targeted wild placement mechanic.

Three bonus symbols is the fixed trigger threshold. The frequency of triggering the bonus is consistent with medium-volatility expectations - it appears regularly enough to matter during a session, but you will not hit it every 10-15 spins.

Volatility and Session Behaviour

With a 96.7% RTP and medium volatility, Triangulation sits in a comfortable middle ground. You will not go 100 spins without a win, but the big cascade sequences that push toward the 40x-per-spin ceiling require patience. The minimum £0.10 bet makes this accessible for low-stakes play, and the £50 maximum suits most recreational players.

The maximum win of 2,000 coins (40x the maximum bet) is modest compared to high-volatility titles like Hellboy or Terminator 2, but the trade-off is steadier, more consistent session play. For players who prefer engagement over the big-win chase, that balance works well.

The cluster mechanic also means there are no dead spins where only 2-3 symbols line up on a payline and pay nothing. If 4 triangles of the same colour are adjacent anywhere on the 16-position grid, that counts - so partial wins occur more often than on a traditional reel layout.

Verdict

Triangulation is a genuine oddity in the Microgaming catalogue - a 2012 game that still holds up because the cluster-pay format feels fresh against a library full of 5x3 reel titles. The 96.7% RTP is honest, the Swap Out Bonus adds a moment of player agency, and the 10x wild multiplier gives each spin a meaningful upside. It is not a high-volatility thrill machine, but as an unusual, low-complexity alternative to standard slots, it delivers exactly what it promises.
