Tinkerbot

Tinkerbot by ELK Studios is a high-volatility cluster pays slot with an RTP of 94% and a maximum win of 10,000x. The game features a 5x5 grid that expands through gameplay, with wins formed when 5 or more symbols connect horizontally or vertically.

Winning clusters are removed to trigger cascades, which generate Botbox symbols. When 3 or more Botboxes land, they release random features; Instant Botboxes trigger a feature without adding to this count. Multisymbols create clusters of identical symbols in a single position and explode surrounding non-winning symbols when they form part of a winning cluster.

The Button symbol triggers one of two effects: Absorb collects all identical symbols into a Multisymbol, or Transform changes all identical symbols into another symbol type. Multiplier symbols appear from Botboxes, increase the global multiplier by their value between x2 and x100, and turn into wilds. Wilds substitute for all symbols and appear randomly or via Botboxes, while Hot Wilds convert several payout symbols into wilds.

The Expand Grid feature, triggered by a Botbox, expands the grid by one row and one reel up to a maximum of 7x7. Bot Frenzy activates when the grid clears of payout symbols, awarding additional Botboxes for enhanced subsequent spins.

Landing 3 scatter symbols triggers 7 free spins, while 4 scatters award 9 Super Bonus free spins starting with a full 7x7 grid and an increased multiplier. Each scatter during free spins grants an extra spin. Multipliers, grid expansions and Botboxes carry over across bonus spins.

X-iter options are available for enhanced gameplay.
