What is the RTP of Triple Nugget Trail Hold and Win?

The game rules state a theoretical payout of 93.83% for normal play. BuyBonus level 1 is 94.17%, level 2 is 94.24% and level 3 is 94.39%.

How do you trigger the Hold and Win Bonus?

Land 3 or more Hold and Win symbols of any type anywhere in the base game. You get 3 spins, and the counter resets to 3 each time a new Hold and Win symbol locks in place.

How much does the bonus buy cost?

There are three levels: 45x, 60x and 87x the bet. At a €2 bet that is €90, €120 and €174. They give 3, 4 or 5 starting Hold and Win symbols with 1, 2 or all 3 features active.

What do the Treasure, Collect and Double Up symbols do?

Treasure attaches a random cashpot worth 5x, 10x, 20x or 100x the bet. Collect takes the total value of all other Hold and Win symbols in view. Double Up doubles the values on all other Hold and Win symbols in view, then gets its own random value.

What happens if the whole grid fills with Hold and Win symbols?

Filling the grid ends the bonus and pays the full grid prize of 1,000x the bet.

What is the bet range in the demo?

The demo bet selector runs from €0.10 to €60.00 per spin on 20 fixed paylines.

Triple Nugget Trail Hold and Win Guide: Rules, Treasure, Collect and Double Up

Triple Nugget Trail Hold and Win slot by Kalamba Games

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Triple Nugget Trail Hold and Win is a Kalamba Games mining slot built around one bonus: a Hold and Win round with three special mine carts sitting on top of the reels. The red Treasure cart, the blue Collect cart and the green Double Up cart each change how the cash nuggets pay once they are switched on.

We played the free demo, read every paytable and rules page, and bought all three BuyBonus levels at a €2 bet. This guide covers the rules as the game states them, the real numbers from our three bought rounds, and what to expect from a game whose base RTP sits below the usual mark.

How Triple Nugget Trail works

The game uses 5 reels, 3 rows and 20 fixed paylines. Line wins pay left to right in succession from the leftmost column, and only the best combination on each payline is paid. Wins from different lines are added together.

The Wild is a stack of dynamite marked WILD. It substitutes for every symbol except the Hold and Win symbols, and in the base game it only lands on columns 2, 3, 4 and 5. Above the reels sit the three carts labelled Treasure, Collect and Double Up, and to the left you see the four cashpot values, which scale with your bet (at €2 they read €10, €20, €40 and €200).

In the demo the bet selector ran from €0.10 to €60.00 per spin, and the paytable values shown on screen follow the bet you have selected.

Paytable in multiples of the bet

The paytable lists euro values at the current bet, so we converted the €2 figures into multiples of the total bet. The old miner is the top symbol: 5 pay 50x, 4 pay 25x and 3 pay 5x. The red lantern pays 10x, 5x and 3x for 5, 4 and 3. The pickaxe pays 8x, 4x and 2x, and the shovel pays 5x, 3x and 1x.

The card royals are much smaller. A and K pay 1.5x for five, 0.7x for four and 0.4x for three. Q, J and 10 pay 0.8x, 0.4x and 0.2x. In other words, line hits keep the session ticking over and the real money sits in the Hold and Win bonus.

The four Hold and Win symbols

There are four types of Hold and Win symbol, and each one is tied to specific columns in the base game.

Standard Hold and Win symbols are plain gold nuggets with a random cash value of 0.5x, 0.8x, 1x, 1.5x, 2x, 2.5x, 3x or 4x the bet. In the base game they appear on the first and last column only.

Treasure Hold and Win symbols (red gem) trigger a CASHPOT prize when they hit during the bonus. One of the four cashpots is picked at random and its value, 5x, 10x, 20x or 100x the bet, is attached to the symbol. They appear on column 2 in the base game.

Collect Hold and Win symbols (blue gem) take a value equal to the total of all other Hold and Win symbols in view when they land during the bonus. They appear on column 3 in the base game.

Double Up Hold and Win symbols (green gem) multiply by 2 the cash values on all other Hold and Win symbols in view when they land during the bonus. After that, a random cash value is attached to the Double Up symbol itself. They appear on column 4 in the base game.

The rules state that each special symbol's effect also applies to the one that started the bonus, so a gem in the trigger can pay out from the first spin.

Hold and Win Bonus

Three or more Hold and Win symbols of any type, anywhere in the base game, trigger the Hold and Win Bonus with 3 initial spins. The symbols that started it lock in place for the whole round.

Every new Hold and Win symbol that lands also locks, and each time one does the spin counter resets to 3. The round ends when you run out of spins or when all 15 positions are filled. Filling the grid pays the full grid prize of 1,000x the bet, which shows as €2,000 on the left of the bonus screen at a €2 stake.

The three carts on top tell you which gem features are active in that round. A cart that lights up means its gem type can drop and do its job; the intro screen spells out how many features were activated before the first spin.

BuyBonus options and what we got

The shopping cart button opens the BuyBonus menu with three levels. Prices scale with the bet; at €2 they were €90, €120 and €174, which works out to 45x, 60x and 87x the bet. During a bought round, pays are based on the bet shown before you bought.

Level 1 (45x) starts the bonus with 3 Hold and Win symbols and 1 active feature guaranteed, with a stated RTP of 94.17%. Level 2 (60x) gives 4 Hold and Win symbols and 2 active features guaranteed, at 94.24%. Level 3 (87x) gives 5 Hold and Win symbols with all 3 features active, at 94.39%. All three levels return a little more on paper than the 93.83% base game.

Our level 1 buy rolled the Treasure feature. The round paid €40.60, about 20x the bet, so less than half of the €90 price came back. The level 2 buy activated Double Up and Collect and paid €31.00, about 15.5x the bet against a 60x cost. The level 3 buy, with all three carts lit, showed a Super Win of €100.80, about 50x the bet, still short of the 87x price. That is three single rounds, €384 spent and €172.40 returned, not an average. It does show that a guaranteed feature is not a guaranteed profit.

RTP, top prize and bet range

The game rules list a theoretical payout of 93.83% for normal play, rising to 94.17%, 94.24% and 94.39% for BuyBonus levels 1, 2 and 3. That base figure is low next to most current slots, so this is a game to play for the feature design rather than for value.

The biggest prize the rules name is the 1,000x full grid prize, plus the 100x top cashpot that a Treasure gem can attach. The rules screens we saw do not state an overall maximum win or a volatility rating, so we will not guess one. The demo bet range was €0.10 to €60.00.

Our verdict

Triple Nugget Trail Hold and Win takes a familiar cash-collect format and makes it more readable: three colour-coded carts, one job each, and a buy menu that tells you exactly how many features you are paying for. We like that each gem type is locked to its own column in the base game, so you can see a trigger building. The weak point is the maths. A 93.83% base RTP is low, the bought levels only reach 94.39%, and all three of our bought rounds returned less than they cost. Treat it as a fun demo to learn the Treasure, Collect and Double Up combinations, not as a game with a generous return.
