Laravel custom captcha

Hi, I'm actually using google recaptcha to protect our site from bots on forms and so on, but I found that it slow down a lot the site especially on mobile devices, so I would like a custom one. No laravel package or low-effort captcha. We want a custom one to add into our laravel helper based on some features: - Slide on the form as captcha. - After slide will appear a number to write into the captcha field. - Form must be submitted after a [value] of time, in less will be automatically rejected. - If the visitor has our site cookie enabled, the option above is off. - Modal style based on our current site style. - Function to check if the visitor successfully passed captcha or not to implement in our controllers.
