Mad Scientist: Breaking Beakers – Hold & Win is a five-reel, four-row online slot from BetSoft with 10 paylines and a high-volatility model. The game uses a laboratory setting with beaker symbols, animated explosions and science-themed character icons. Its published RTP is 96.24%.
The main bonus is the Hold & Win feature, which starts when six or more scattered Beaker symbols land and awards three respins. During the feature, beakers can hold cash values or jackpot labels, while special symbols such as ALL Beaker, Cross Beaker and Extra Beaker change how those values are collected or increased. A reel-spanning Wild symbol also appears, although it does not substitute for Beaker symbols.
A demo version is available near the launcher, allowing players to play for free and practice before playing for real money. The slot also uses Mystery symbols, which turn into one random symbol before a spin, and its beaker drops can reset respins when new wins appear.
