Mine Defender is a slot game from ELK Studios built on a 5-row by 6-column grid. The game combines dropping symbols, scatter wins, wilds and multipliers with coin wins and a stated top payout of 10,000x. The RTP is listed at 94%, with bets ranging from 0.2 to 100.
Collecting three bonus symbols triggers the Mass Attack bonus game, played on a circular field around the Hero. The Hero starts with three lives while enemy robots move inward, and Hero features can add shots, lives or projectiles. A final boss battle follows after 50 enemies are defeated, with a 3x3 boss carrying 50 lives and awarding a trophy coin multiplied by the global multiplier.
This Mine Defender demo version lets players play for free and practice before playing for real money. X-iter modes are also part of the design, offering different entry points into the action with higher bonus-trigger chances or more ammunition.
