Dam Beavers Slot by ELK Studios

No paylines. No ways-to-win counter. Four colored beavers walk around the grid picking up fruit that matches their color - strawberries for one, blueberries for another, oranges and apples for the other two. That is the entire pay system. ELK calls it CollectR, and it plays more like a board game than anything you would find on a standard casino lobby page. The grid itself is part of the progression: four floor levels expand it step by step, with hidden 2x2 Breaking Points under the floorboards acting as the key to advancing. Uncover one completely and the dam opens up to the next floor, adding rows and columns each time.

Floorboards hide more than just Breaking Points. Multi-tile Coins (sized anywhere from 2x2 up to 8x8) sit underneath, paying out once every covering tile is smashed away by beaver movement. Passages teleport beavers across the board. And on the final floor, one specific Coin hides the full 10,000x payout - reveal it and the round ends instantly. Beaver Night Fever triggers when you clear every floorboard from a single floor: all symbols drop off and come back at upgraded payout levels. Floor 1 clears bump payouts to level 5, Floor 2 to level 6, Floor 3 to level 7. It is a satisfying reset that can completely change the math of whatever floor you are working through.

A collection meter tracks fruit pickups and unlocks reward cards - Wild Scatter, Refresh, or Symbol Swap - with up to 3 stacked at once. Pickup symbols add wrinkles: Fireworks upgrade a beaver's fruit payout level, TNT blows out floorboards from below, and the Blender fills the meter instantly. Three Bonus symbols trigger 5 Free Drops where floor progress, meter state, and payout levels all carry over. Retriggerable with no cap.

The X-iter menu is where things get interesting for anyone who wants to skip the slow early floors. At 10x your bet, Eager Beaver jumps straight to Floor 2 at payout level 2. Dambuster (25x) starts on Floor 3. The 500x Super Bonus buys Free Drops already on Floor 3 - one floor away from the hidden max win Coin. Bright cartoon palette, chunky beaver characters, wooden dam textures everywhere. It looks like a kids' game and plays like a spreadsheet. Huff N Puff CollectR uses the same base engine if you want a different theme on the same system.
