Amalgam includes instructions as well as various customisation settings. It even includes a community section for user-submitted tips and routines. AMALGAM INCLUDES: * Streets * Streets is finally back! John Archer has given his exclusive permission for this remake of his popular Streets app, which now incorporates new features including a modernised real map and a new "gyro crib". - Divine where in the world your spectator is thinking of! - A book test with no memory work required. - A new "legitimate mode" which supports all languages. * TimedOut * A customisable prediction effect that's all in your spectator's hands. Predict a number, dice roll, ESP symbol, star sign or more. - Prediction can be an image in your Photos or perhaps a drawing. - After making your prediction, you do not touch the phone again. - No Internet or Bluetooth required: nothing is sent to or from the device. - Your spectator checks the prediction themselves: the phone remains in their hands! - No voice recognition! - Perfect for pairing with other electronic mentalism effects: reveal a photo from two days ago of you predicting their dice roll, which even they don't know yet! * Watch * A revelation of a freely chosen time. Your spectator zooms in to a wristwatch in a photograph to find it's set to the time they just named. - Customisable: use your own photo. - Any time can be named to the minute. - Novel method: no voice recognition or unjustified inputs. * Word Search * Seemingly demonstrate superhuman memory abilities with this word search game from Harry De Cruz. Although you only look at the word search for a couple of seconds, you can reveal the positions and directions of all words hiding within. - Method keeps memory work to a minimum: if you know the alphabet, you can perform this effect. - No need to secretly obtain information during the effect. - Phone remains in the spectator's hands. * Inertia * Force text, photos and videos on any website, without hiding the screen from the spectator. Inertia works great as a prediction effect, or combined with your favourite revelation. - Predict a word on any website. - Force photos or videos on Instagram. - Reveal you predicted a selected Tweet, movie or Instagram post. * OneStopShop * This fully customisable effect allows you to force a product of your choosing from an online store. - Novel input method combining old and new mechanics. - Multiple built-in presets, or create your own. - Force multiple playing card back designs, thanks to Theory11, Daniel Madison and Patrick Kun. - Built-in clothing preset is perfect to combine with physical effects, such as Dresscode by Calen Morelli. * ChoiceMail * Your spectator's selection is impossibly revealed when listening to a received audio message. - Input mechanism allows you to secretly code the reveal in performance. - Novel input peek system is hidden in plain sight. - HUGE thanks go to AGT winner Shin Lim, who has recorded the built-in presets! - Also fully customisable with custom presets. * Amped * Using a combination of screenshots, Amped lets you demonstrate your apparent superhuman powers over technology. - Included settings allow for multiple customisation options. - Ends clean - device can be fully inspected at the end of the performance. - Combine with a Charge Card (sold separately) for a physical effect. MORE INFO: Each effect in Amalgam includes detailed in-app instructions and settings. The included effects are for entertainment purposes only, designed for professional performers.
