You need to add the options in the ion-slides ponent as shown in their docs.

<ion-slides [options]="option1">
    <ion-slide *ngFor="let slide of slides; let last = last">
        <img [src]="slide.image" class="slide-image" />
        <h2 class="slide-title" [innerHTML]="slide.title" style=""></h2>
        <p [innerHTML]="slide.description"></p>

        <div id="skip-b">
            <button (click)="dismiss()">
      {{last ? "Let's Begin" : "Skip" }}
      <ion-icon name="arrow-forward"></ion-icon>
    </button>
        </div>
    </ion-slide>
</ion-slides>

In the new version of ionic we can easily achieve vertical scroll by passing [options] value to <ion-slides>.

Here is an example.

// page.ts
export class SlideClass {
  slideOptions = {
    direction: 'vertical',
  };
  constructor(){}
 
}

// html file
<ion-slides [options]="slideOptions">

More option we can found here more slide options

you can make your slides vertical by adding ''direction'' parameter.

<ion-slides direction="vertical">

</ion-slides>

by default slides are horizontal.
